+# Classes
+
+Traditional JavaScript focuses on functions and prototype-based inheritance as the basic means of building up reusable components, 
+but this may feel a bit awkward to programmers more comfortable with an object-oriented approach, where classes inherit functionality 
+and objects are built from these classes.
+
+Starting with ECMAScript 2015, also known as ECMAScript 6, JavaScript programmers will be able to build their applications using 
+this object-oriented class-based approach. TypeScript, allows you to use these techniques now, compiling them 
+down to JavaScript that works across all major browsers and platforms, without having to wait for the next version of JavaScript.
+
+Let's take a look at a simple class-based example:
+
+```ts
+class Greeter {
+    greeting: string;
+    constructor(message: string) {
+        this.greeting = message;
+    }
+    greet() {
+        return "Hello, " + this.greeting;
+    }
+}
+
+let greeter = new Greeter("world");
+```
+
+We declare a new class `Greeter`. This class has three members: a property called `greeting`, a constructor, and a method `greet`.
+
+You'll notice that in the class when we refer to one of the members of the class we prepend `this.`.
+This denotes that it's a member access.
+
+In the last line we construct an instance of the `Greeter` class using `new`.
+This calls into the constructor we defined earlier, creating a new object with the `Greeter` shape, and running the constructor to initialize it.
+
+# Inheritance
+
+### ~hint
+### Inheritance is not supported yet for the micro:bit. Coming soon...
+### ~
+
+In TypeScript, we can use common object-oriented patterns.
+Of course, one of the most fundamental patterns in class-based programming is being able to extend existing classes to create new ones using inheritance.
+
+Let's take a look at an example:
+
+```ts
+class Animal {
+    name: string;
+    constructor(theName: string) { this.name = theName; }
+    move(distanceInMeters: number = 0) {
+        console.log(`${this.name} moved ${distanceInMeters}m.`);
+    }
+}
+
+class Snake extends Animal {
+    constructor(name: string) { super(name); }
+    move(distanceInMeters = 5) {
+        console.log("Slithering...");
+        super.move(distanceInMeters);
+    }
+}
+
+class Horse extends Animal {
+    constructor(name: string) { super(name); }
+    move(distanceInMeters = 45) {
+        console.log("Galloping...");
+        super.move(distanceInMeters);
+    }
+}
+
+let sam = new Snake("Sammy the Python");
+let tom: Animal = new Horse("Tommy the Palomino");
+
+sam.move();
+tom.move(34);
+```
+
+This example covers quite a few of the inheritance features in TypeScript that are common to other languages.
+Here we see the `extends` keywords used to create a subclass. 
+You can see this where `Horse` and `Snake` subclass the base class `Animal` and gain access to its features.
+
+Derived classes that contain constructor functions must call `super()` which will execute the constructor function on the base class.
+
+The example also shows how to override methods in the base class with methods that are specialized for the subclass.
+Here both `Snake` and `Horse` create a `move` method that overrides the `move` from `Animal`, giving it functionality specific to each class.
+Note that even though `tom` is declared as an `Animal`, since its value is a `Horse`, when `tom.move(34)` calls the overriding method in `Horse`:
+
+```Text
+Slithering...
+Sammy the Python moved 5m.
+Galloping...
+Tommy the Palomino moved 34m.
+```
+
+# Public, private, and protected modifiers
+
+## Public by default
+
+In our examples, we've been able to freely access the members that we declared throughout our programs.
+If you're familiar with classes in other languages, you may have noticed in the above examples 
+we haven't had to use the word `public` to accomplish this; for instance, 
+C# requires that each member be explicitly labeled `public` to be visible.
+In TypeScript, each member is `public` by default.
+
+You may still mark a member `public` explicitly.
+We could have written the `Animal` class from the previous section in the following way:
+
+```ts
+class Animal {
+    public name: string;
+    public constructor(theName: string) { this.name = theName; }
+    public move(distanceInMeters: number) {
+        console.log(`${this.name} moved ${distanceInMeters}m.`);
+    }
+}
+```
+
+## Understanding `private`
+
+When a member is marked `private`, it cannot be accessed from outside of its containing class. For example:
+
+```ts
+class Animal {
+    private name: string;
+    constructor(theName: string) { this.name = theName; }
+}
+
+new Animal("Cat").name; // Error: 'name' is private;
+```
+
+TypeScript is a structural type system.
+When we compare two different types, regardless of where they came from, if the types of all members are compatible, then we say the types themselves are compatible.
+
+However, when comparing types that have `private` and `protected` members, we treat these types differently.
+For two types to be considered compatible, if one of them has a `private` member, 
+then the other must have a `private` member that originated in the same declaration.
+The same applies to `protected` members.
+
+Let's look at an example to better see how this plays out in practice:
+
+```ts
+class Animal {
+    private name: string;
+    constructor(theName: string) { this.name = theName; }
+}
+
+class Rhino extends Animal {
+    constructor() { super("Rhino"); }
+}
+
+class Employee {
+    private name: string;
+    constructor(theName: string) { this.name = theName; }
+}
+
+let animal = new Animal("Goat");
+let rhino = new Rhino();
+let employee = new Employee("Bob");
+
+animal = rhino;
+animal = employee; // Error: 'Animal' and 'Employee' are not compatible
+```
+
+In this example, we have an `Animal` and a `Rhino`, with `Rhino` being a subclass of `Animal`.
+We also have a new class `Employee` that looks identical to `Animal` in terms of shape.
+We create some instances of these classes and then try to assign them to each other to see what will happen.
+Because `Animal` and `Rhino` share the `private` side of their shape from the same declaration of 
+`private name: string` in `Animal`, they are compatible. However, this is not the case for `Employee`.
+When we try to assign from an `Employee` to `Animal` we get an error that these types are not compatible.
+Even though `Employee` also has a `private` member called `name`, it's not the one we declared in `Animal`.
+
+## Understanding `protected`
+
+The `protected` modifier acts much like the `private` modifier with the exception that members 
+declared `protected` can also be accessed by instances of deriving classes. For example,
+
+```ts
+class Person {
+    protected name: string;
+    constructor(name: string) { this.name = name; }
+}
+
+class Employee extends Person {
+    private department: string;
+
+    constructor(name: string, department: string) {
+        super(name);
+        this.department = department;
+    }
+
+    public getElevatorPitch() {
+        return `Hello, my name is ${this.name} and I work in ${this.department}.`;
+    }
+}
+
+let howard = new Employee("Howard", "Sales");
+console.log(howard.getElevatorPitch());
+console.log(howard.name); // error
+```
+
+Notice that while we can't use `name` from outside of `Person`, 
+we can still use it from within an instance method of `Employee` because `Employee` derives from `Person`.
+
+A constructor may also be marked `protected`.
+This means that the class cannot be instantiated outside of its containing class, but can be extended. For example,
+
+```ts
+class Person {
+    protected name: string;
+    protected constructor(theName: string) { this.name = theName; }
+}
+
+// Employee can extend Person
+class Employee extends Person {
+    private department: string;
+
+    constructor(name: string, department: string) {
+        super(name);
+        this.department = department;
+    }
+
+    public getElevatorPitch() {
+        return `Hello, my name is ${this.name} and I work in ${this.department}.`;
+    }
+}
+
+let howard = new Employee("Howard", "Sales");
+let john = new Person("John"); // Error: The 'Person' constructor is protected
+```
+
+# Readonly modifier
+
+You can make properties readonly by using the `readonly` keyword.
+Readonly properties must be initialized at their declaration or in the constructor.
+
+```ts
+class Octopus {
+    readonly name: string;
+    readonly numberOfLegs: number = 8;
+    constructor (theName: string) {
+        this.name = theName;
+    }
+}
+let dad = new Octopus("Man with the 8 strong legs");
+dad.name = "Man with the 3-piece suit"; // error! name is readonly.
+```
+
+## Parameter properties
+
+In our last example, we had to declare a readonly member `name` and a constructor parameter `theName` in the `Octopus` class, and we then immediately set `name` to `theName`.
+This turns out to be a very common practice.
+*Parameter properties* let you create and initialize a member in one place.
+Here's a further revision of the previous `Octopus` class using a parameter property:
+
+```ts
+class Octopus {
+    readonly numberOfLegs: number = 8;
+    constructor(readonly name: string) {
+    }
+}
+```
+
+Notice how we dropped `theName` altogether and just use the shortened `readonly name: string` parameter on the constructor to create and initialize the `name` member.
+We've consolidated the declarations and assignment into one location.
+
+Parameter properties are declared by prefixing a constructor parameter with an accessibility modifier or `readonly`, or both.
+Using `private` for a parameter property declares and initializes a private member; likewise, the same is done for `public`, `protected`, and `readonly`.

+# Functions
+
+Functions are the fundamental building block of programs. Here is the simplest
+way to make a function that adds two numbers:
+
+```ts
+// Named function
+function add(x : number, y : number) {
+    return x + y;
+}
+
+basic.showNumber(add(1, 2))
+```
+
+### ~ hint
+For the micro:bit, you must specify a [type](/js/types) for each function parameter. 
+### ~ 
+
+Functions can refer to variables outside of the function body.
+When they do so, they're said to `capture` these variables.
+
+```ts
+let z = 100;
+
+function addToZ(x: number, y: number) {
+    return x + y + z;
+}
+
+basic.showNumber(addToZ(1, 2))
+```
+
+## Typing the function
+
+Let's add a return type to our add function:
+
+```ts
+function add(x: number, y: number): number {
+    return x + y;
+}
+```
+
+TypeScript can figure the return type out by looking at the return statements, so you can optionally leave this off in many cases.
+
+# Optional and Default Parameters
+
+In TypeScript, the number of arguments given to a function has to match the number of parameters the function expects.
+
+```ts
+function buildName(firstName: string, lastName: string) {
+    return firstName + " " + lastName;
+}
+
+let result1 = buildName("Bob");                  // error, too few parameters
+let result2 = buildName("Bob", "Adams", "Sr.");  // error, too many parameters
+let result3 = buildName("Bob", "Adams");         // ah, just right
+```
+
+In JavaScript, every parameter is optional, and users may leave them off as they see fit.
+When they do, their value is `undefined`.
+We can get this functionality in TypeScript by adding a `?` to the end of parameters we want to be optional.
+For example, let's say we want the last name parameter from above to be optional:
+
+```ts
+function buildName(firstName: string, lastName?: string) {
+    if (lastName)
+        return firstName + " " + lastName;
+    else
+        return firstName;
+}
+
+let result1 = buildName("Bob");                  // works correctly now
+let result2 = buildName("Bob", "Adams", "Sr.");  // error, too many parameters
+let result3 = buildName("Bob", "Adams");         // ah, just right
+```
+
+Any optional parameters must follow required parameters.
+Had we wanted to make the first name optional rather than the last name, we would need to change the order of parameters in the function, putting the first name last in the list.
+
+In TypeScript, we can also set a value that a parameter will be assigned if the user does not provide one, or if the user passes `undefined` in its place.
+These are called default-initialized parameters.
+Let's take the previous example and default the last name to `"Smith"`.
+
+```ts
+function buildName(firstName: string, lastName = "Smith") {
+    return firstName + " " + lastName;
+}
+
+let result1 = buildName("Bob");                  // works correctly now, returns "Bob Smith"
+let result2 = buildName("Bob", undefined);       // still works, also returns "Bob Smith"
+let result3 = buildName("Bob", "Adams", "Sr.");  // error, too many parameters
+let result4 = buildName("Bob", "Adams");         // ah, just right
+```
+
+Default-initialized parameters that come after all required parameters are treated as optional, and just like optional parameters, can be omitted when calling their respective function.
+This means optional parameters and trailing default parameters will share commonality in their types, so both
+
+```ts
+function buildName(firstName: string, lastName?: string) {
+    // ...
+}
+```
+
+and
+
+```ts
+function buildName(firstName: string, lastName = "Smith") {
+    // ...
+}
+```
+
+share the same type `(firstName: string, lastName?: string) => string`.
+The default value of `lastName` disappears in the type, only leaving behind the fact that the parameter is optional.
+
+Unlike plain optional parameters, default-initialized parameters don't *need* to occur after required parameters.
+If a default-initialized parameter comes before a required parameter, users need to explicitly pass `undefined` to get the default initialized value.
+For example, we could write our last example with only a default initializer on `firstName`:
+
+```ts
+function buildName(firstName = "Will", lastName: string) {
+    return firstName + " " + lastName;
+}
+
+let result1 = buildName("Bob");                  // error, too few parameters
+let result2 = buildName("Bob", "Adams", "Sr.");  // error, too many parameters
+let result3 = buildName("Bob", "Adams");         // okay and returns "Bob Adams"
+let result4 = buildName(undefined, "Adams");     // okay and returns "Will Adams"
+```
+
+# Rest Parameters
+
+Required, optional, and default parameters all have one thing in common: they talk about one parameter at a time.
+Sometimes, you want to work with multiple parameters as a group, or you may not know how many parameters a function will ultimately take.
+In JavaScript, you can work with the arguments directly using the `arguments` variable that is visible inside every function body.
+
+In TypeScript, you can gather these arguments together into a variable:
+
+```ts
+function buildName(firstName: string, ...restOfName: string[]) {
+    return firstName + " " + restOfName.join(" ");
+}
+
+let employeeName = buildName("Joseph", "Samuel", "Lucas", "MacKinzie");
+```
+
+*Rest parameters* are treated as a boundless number of optional parameters.
+When passing arguments for a rest parameter, you can use as many as you want; you can even pass none.
+The compiler will build an array of the arguments passed in with the name given after the ellipsis (`...`), allowing you to use it in your function.
+
+The ellipsis is also used in the type of the function with rest parameters:
+
+```ts
+function buildName(firstName: string, ...restOfName: string[]) {
+    return firstName + " " + restOfName.join(" ");
+}
+
+let buildNameFun: (fname: string, ...rest: string[]) => string = buildName;
+```

-## The Semicolon
+### The semicolon 
 
-Coming soon...
+In JavaScript, the semicolon (;) is used to terminate (or end) a statement. However, in most
+cases, the semicolon is optional and can be omitted. So both code sequences below are 
+legal:
 
+```typescript
+basic.showNumber(1)
+basic.showNumber(2)
+```
+
+```typescript
+basic.showNumber(1); 
+basic.showNumber(2);
+```
+
+### The empty statement
+
+In JavaScript, there is the concept of an *empty statement*, which is whitespace followed by
+a semicolon in the context where a statement is expected.
+So, the following code is an infinite loop
+followed by a call to `showNumber` that will never execute:
+```typescript
+while(true) ;  
+basic.showNumber(1);
+```
+
+
+### ~hint
+For the micro:bit, we don't allow a program to contain an empty statement, such as shown above. 
+If you really want an empty statement, you need to use curly braces to delimit an empty statement block:
+```typescript
+while(true) { } 
+basic.showNumber(1);
+```

+# Types
+
+For programs to be useful, we need to be able to work with some of the simplest units of data: 
+numbers, strings, structures, boolean values, and the like.
+
+# Boolean
+
+The most basic datatype is the simple true/false value, which is called a `boolean` value.
+
+```ts
+let isDone: boolean = false;
+```
+
+# Number
+
+### ~ hint 
+In JavaScript, `numbers` are floating point values.
+However, for the micro:bit, `numbers` are integer values.
+### ~
+
+Integer values can be specified via decimal, hexadecimal and octal notation:
+
+```ts
+let decimal: number = 42;
+let hex: number = 0xf00d;
+let binary: number = 0b1010;
+let octal: number = 0o744;
+```
+
+# String
+
+As in other languages, we use the type `string` to refer to textual data.
+Use double quotes (`"`) or single quotes (`'`) to surround string data.
+
+```ts
+let color: string = "blue";
+color = 'red';
+```
+
+You can also use *template strings*, which can span multiple lines and have embedded expressions.
+These strings are surrounded by the backtick/backquote (`` ` ``) character, and embedded expressions are of the form `${ expr }`.
+
+```ts
+let fullName: string = `Bob Bobbington`;
+let age: number = 37;
+let sentence: string = `Hello, my name is ${ fullName }.
+
+I'll be ${ age + 1 } years old next month.`
+```
+
+This is equivalent to declaring `sentence` like so:
+
+```ts
+let sentence: string = "Hello, my name is " + fullName + ".\n\n" +
+    "I'll be " + (age + 1) + " years old next month."
+```
+
+# Array
+
+Arrays allow you to work with an expandable sequence of values, addressed by an integer-valued index.
+Array types can be written in one of two ways.
+In the first, you use the type of the elements followed by `[]` to denote an array of that element type:
+
+```ts
+let list: number[] = [1, 2, 3];
+```
+
+The second way uses a generic array type, `Array<elemType>`:
+
+```ts
+let list: Array<number> = [1, 2, 3];
+```
+
+### ~hint
+For the micro:bit, all elements of an array must have the same type.
+### ~
+
+
+# Enum
+
+A helpful addition to the standard set of datatypes from JavaScript is the `enum`.
+As in languages like C#, an enum is a way of giving more friendly names to sets of numeric values.
+
+```ts
+enum Color {Red, Green, Blue};
+let c: Color = Color.Green;
+```
+
+By default, enums begin numbering their members starting at `0`.
+You can change this by manually setting the value of one of its members.
+For example, we can start the previous example at `1` instead of `0`:
+
+```ts
+enum Color {Red = 1, Green, Blue};
+let c: Color = Color.Green;
+```
+
+Or, even manually set all the values in the enum:
+
+```ts
+enum Color {Red = 1, Green = 2, Blue = 4};
+let c: Color = Color.Green;
+```
+
+# Any
+
+The TypeScript type `any` is not supported in the micro:bit.
+
+
+# Void
+
+`void` is the absence of having any type at all.
+You may commonly see this as the return type of functions that do not return a value:
+
+```ts
+function warnUser(): void {
+    basic.showString("This is my warning message");
+}
+```
+
+Declaring variables of type `void` is not useful.
+
+# Type Inference
+
+In TypeScript, there are several places where type inference is used to provide type information when there is
+no explicit type annotation. For example, in this code
+
+```ts
+let x = 3;
+let y = x + 3
+```
+
+The type of the `x` variable is inferred to be `number`. Similarly, the type of `y` variable also is inferred to be `number`.
+This kind of inference takes place when initializing variables and members, 
+setting parameter default values, and determining function return types.

+# Variable Declarations
+
+Declaring a variable in JavaScript has always traditionally been done with the `var` keyword.
+
+```typescript
+var a = 10;
+```
+
+The `var` construct has some [problems](http://www.typescriptlang.org/docs/handbook/variable-declarations.html), 
+which is why `let` statements were introduced. Apart from the keyword used, `let` statements are written 
+the same way `var` statements are.
+
+```typescript
+let a = 10;
+```
+
+The key difference is not in the syntax, but in the semantics, which we'll now dive into.
+
+## Block-scoping
+
+When a variable is declared using `let`, it uses what some call *lexical-scoping* or *block-scoping*.
+Unlike variables declared with `var` whose scopes leak out to their containing function, 
+block-scoped variables are not visible outside of their nearest containing block or `for`-loop.
+
+```typescript
+function f(input: boolean) {
+    let a = 100;
+
+    if (input) {
+        // Still okay to reference 'a'
+        let b = a + 1;
+        return b;
+    }
+
+    // Error: 'b' doesn't exist here
+    return b;
+}
+```
+
+Here, we have two local variables `a` and `b`.
+`a`'s scope is limited to the body of `f` while `b`'s scope is limited to the containing `if` statement's block.
+
+Another property of block-scoped variables is that they can't be read or written to before they're actually declared.
+While these variables are "present" throughout their scope, all points up until their declaration are part of their *temporal dead zone*.
+This is just a sophisticated way of saying you can't access them before the `let` statement, and luckily TypeScript will let you know that.
+
+```typescript
+a++; // illegal to use 'a' before it's declared;
+let a;
+```
+
+## Re-declarations
+
+With `var` declarations, it doesn't matter how many times you declare your variables, you just get one:
+
+```typescript
+var x = 10;
+var x = 20; 
+```
+
+In the above example, all declarations of `x` actually refer to the *same* `x`, and this is perfectly valid.
+This often ends up being a source of bugs. Thankfully, `let` declarations are not as forgiving.
+
+```typescript
+let x = 10;
+let x = 20; // error: can't re-declare 'x' in the same scope
+```
+
+## Shadowing
+
+The act of introducing a new name in a more deeply nested scope is called *shadowing*.
+It is a bit of a double-edged sword in that it can introduce certain bugs on its own in the 
+event of accidental shadowing, while also preventing certain bugs.
+For instance, imagine a `sumMatrix` function using `let` variables.
+
+```typescript
+function sumMatrix(matrix: number[][]) {
+    let sum = 0;
+    for (let i = 0; i < matrix.length; i++) {
+        var currentRow = matrix[i];
+        for (let i = 0; i < currentRow.length; i++) {
+            sum += currentRow[i];
+        }
+    }
+
+    return sum;
+}
+```
+
+This version of the loop will actually perform the summation correctly because the inner loop's `i` shadows `i` from the outer loop.
+Shadowing should *usually* be avoided in the interest of write clearer code, such as
+
+```typescript
+function sumMatrix(matrix: number[][]) {
+    let sum = 0;
+    for (let i = 0; i < matrix.length; i++) {
+        var currentRow = matrix[i];
+        for (let j = 0; j < currentRow.length; j++) {
+            sum += currentRow[j];
+        }
+    }
+
+    return sum;
+}
+```
+While there are some scenarios where it may be fitting to take advantage of it, you should use your best judgement.
+
+# `const` declarations
+
+`const` declarations are another way of declaring variables.
+
+```typescript
+const numLivesForCat = 9;
+```
+
+They are like `let` declarations but, as their name implies, their value cannot be changed once they are bound.
+In other words, they have the same scoping rules as `let`, but you can't re-assign to them.

-# NeoPixel driver
-
-This library provides a driver for various Neo Pixel LED strips, 
-see https://www.adafruit.com/category/168
-
-NeoPixels consist of a number of RGB LEDs, every one of them controlled
-separately.  
-
-## Basic usage
-
-```blocks
-// Create a NeoPixel driver - specify the number of LEDs:
-let strip = neopixel.create(DigitalPin.P0, 24)
-
-// set pixel colors
-strip.setPixelColor(0, 255, 255, 255) // white
-strip.setPixelColor(1, 255, 0, 0)     // red
-strip.setPixelColor(2, 0, 255, 0)     // green
-strip.setPixelColor(3, 0, 0, 255)     // blue
-
-// send the data to the strip
-strip.show()
-```
-
-Use `strip.setBrigthness()` to lower the brightness (it's maxed out by default).
-
-Use `strip.shift()` or `strip.rotate()` to shift the lights around.
-
-## Example: Using accelerometer to control colors
-
-This little program will let the position of the microbit control the color of the first LED.
-This first LED will then get shifted further away every 100ms.
-
-```blocks
-let strip = neopixel.create(DigitalPin.P0, 24)
-while (true) {
-    let x = input.acceleration(Dimension.X) / 2
-    let y = input.acceleration(Dimension.Y) / 2
-    let z = input.acceleration(Dimension.Z) / 2
-    strip.setPixelColor(0, x, y, -z);
-    strip.shift(1);
-    strip.show();
-    basic.pause(100);
