-## Universal Windows App
-
-The Windows 10 app is a [Universal Windows Hosted Web App](https://microsoftedge.github.io/WebAppsDocs/en-US/win10/CreateHWA.htm)
-that wraps ``codethemicrobit.com`` and provides additional features.
-
 ### Building
 
 * Install Visual Studio 2015 Update 2 or higher. Make sure the Windows 10 templates are installed.
 * open the ``win10/app.sln`` solution and launch the ``codethemicrobit`` project.
 
+## Testing
+
+The build automatically runs the following:
+
+* make sure the built-in packages compile
+* `pxt run` in `libs/lang-test*` - this will run the test in command line runner; 
+  there is a number of asserts in both of these
+* `pxt testdir` in `tests` - this makes sure all the files compile and generates .hex files
+* run the TD->TS converter on a number of test scripts from `microbit.co.uk` and make sure the results compile
+
+To test something on the device:
+
+* do a `pxt deploy` in `libs/lang-test*` - they should show `1` or `2` on the screen (and not unhappy face)
+* run `pxt testdir` in `tests` and deploy some of the hex files from `tests/built`
+
+The `lang-test0` source comes from the `pxt-core` package. It's also tested with `pxt run` there.

The scheduler uses a timer built into the micro:bit hardware to interrupt execution every 6 milliseconds and poll the inputs, which is more than fast enough to catch the quickest press of a button.

 We will call this “passing control of execution” rather than “passing the ball”.  However, in the world of the micro:bit, the concurrently executing subprograms are not aware of each other, so they don’t actually pass control directly to one another.  Rather they pass control of execution back to the scheduler and the scheduler determines the subprogram to pass control to next.  The programmer inserts a call to the `pause` function to indicate a point in the subprogram where control of execution passes to the scheduler. Also, when a subprogram ends execution, control passes to the scheduler.

 The `forever` loop actually is a function that takes a subprogram (an *Action* in Touch Develop) as a parameter. The function uses the `control -> in background` function of the micro:bit runtime to queue a `while true` loop for execution by the scheduler. The while loop has two statements. The first statement runs the subprogram represented by the `body` parameter. The second statement passes control to the scheduler (requesting to “sleep” for 20 milliseconds).

+# Frequently asked questions
+
+# What is the language supported for the micro:bit?
+
+For the micro:bit, we support a "static" subset of TypeScript (itself a superset of JavaScript):
+
+## Supported language features
+
+* variables with `let`, `const`, and `var`
+* functions with lexical scoping and recursion
+* top-level code in the file; hello world really is `console.log("Hello world")`
+* `if ... else if ... else` statements
+* `while` and `do ... while` loops
+* `for(;;)` loops (see below about `for ... in/of`)
+* `break/continue`; also with labeled loops
+* `switch` statement (on numbers only)
+* `debugger` statement for breakpoints
+* conditional operator `? :`; lazy boolean operators
+* namespaces (a form of modules) 
+* all arithmetic operators (including bitwise operators); note that in microcontroller targets
+  all arithmetic is performed on integers, also when simulating in the browser
+* strings (with a few common methods)
+* [string templates](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) (`` `x is ${x}` ``)
+* arrow functions `() => ...`
+* classes with fields, methods and constructors; `new` keyword
+* array literals `[1, 2, 3]`
+* enums
+
+## Unsupported language features
+
+We generally stay away from the more dynamic parts of JavaScript. 
+Things you may miss and we may implement:
+
+* exceptions (`throw`, `try ... catch`, `try ... finally`)
+* `for ... of` statements
+* object literals `{ foo: 1, bar: "two" }`
+* method-like properties (get/set accessors)
+* class inheritance
+
+For JS-only targets we may implement the following:
+
+* regular expressions
+* classes implementing interfaces
+
+Things that we are not very likely to implement:
+
+* file-based modules (`import * from ...`, `module.exports` etc); we do support namespaces
+* spread operator
+* `yield` expression and ``function*``
+* `await` expression and `async function`
+* `typeof` expression
+* tagged templates ``tag `text ${expression} more text` ``; regular templates are supported
+* binding with arrays or objects: `let [a, b] = ...; let { x, y } = ...`
+* `with` statement
+* `eval`
+* `delete` statement
+* `for ... in` statements
+* JSX (HTML as part of JavaScript)

 In programming we use an ‘if’ statement: if this condition is met, do something. Lets add an if statement to the code we had before; the BBC Micro:bit will wait for the user to press a button before showing the image.
 
-### Write the code

-Click the **if** category and drag an `if/do` block. Drag the`show string` block we wrote previously into the `do` section of the block. Next click the **input** tab and drag a `button pressed` block, connect it to the open jigsaw of the `if` block. This is our criteria: `if A button is pressed`. We can change which button (button A or B) by clicking the arrow next to ‘A’ and changing the value. This means our BBC micro:bit is waiting for button A (the left button) to be pressed. Finally go to the **basic** tab and drag a `forever` block, and attach all our code inside. We add this block to ensure the BBC micro:bit is always waiting to show us this message, not just once. Your code should look like this:

The BBC micro:bit checks if the user is pressing the left button, if the user is not then the “Press the button!” message will scroll across the LEDs. If the user is pressing the button then the “hello, world!” message will scroll across the screen. Check this in the simulator or attach the BBC micro:bit to the computer then click **compile** to send the code onto the BBC micro:bit.

-## Graphics Challenges [3]
-
-Using the knowledge you have learnt from the [rendering graphics](/lessons/graphics) section, try creating an algorithm to draw these shapes. Before you write the code try to figure out how the BBC micro:bit will be thinking to plot these points. For example, with our diagonal line – “count up from 0 to 4 by 1, and plot points x=i and y=i”.
-
-* Another diagonal line
-* A square going around the board
-* A filled square
-* A square which unplots itself after

-
-## Electronic Dice Challenge [5]
-
-Using the code in the Random Numbers tutorial in Section 6, or your own algorithm, create an electronic dice that displays the values appropriate for a dice (so 1 shows a single LED on in the center, two shows two LEDs on at each corner, etc.). You may want to declare image variables to do this, then check what it is equal to using an ‘if’ statement. Sample code is below.
-
-![](/static/mb/blocks/lessons-4.png)
-
-## Calculator Challenge [6]
-
-Using your knowledge of loops, counters and math, create a calculator.
-
-The calculator should:
-
-* Count the amount of times the user presses the left button before pressing the right button (this is the first value, or valueOne)
-* Count the amount of times the user presses the left button before the right button again (this is the second value, or valueTwo)
-* Scroll through operations (+,-, x and divide) until the user presses the right button to make a choice
-* Perform the calculation
-* Show the entire calculation, for example: 5 + 10 = 15
-
-Sample code is below.

-## Smart watch Challenge [8]
-
-Create a smart watch using the BBC micro:bit. Create a menu where the user presses one button to cycle through options and another button to choose this option. Add applications to this smart watch:
-
-* Calculators
-* Games
-* Random number generators
-

-# blocks - loops
-
-An introduction to Loops for the Block Editor.
-
-We may want to handle the user’s input multiple times or remain waiting for their input for a long time. We use loops to make sure that our code runs multiple times. These can be found in the **Loops** drawer.
-
-### Forever loops
-
-In the Variables tutorial we utilised a forever loop to create a counter:
-
-![](/static/mb/blocks/lessons/blocks-conditions-2.png)
-
-This allows our BBC micro:bit to wait for the user to do something forever, for example wait for the user to press the correct button as the example above shows. If you were creating a quiz, you may want to loop forever until the user presses the correct button or answers the question.
-
-### Repeat Loops
-
-Repeat loops allow code to happen a certain amount of times. You may want to create a quiz that only gives the user a few tries to get the correct answer, for example. The number can be changed to facilitate your code.
-
-![](/static/mb/blocks/lessons/loops-0.png)
-
-The code above will scroll the message, “Hello world” three times.
-
-### While & Until loops
-
-The ‘repeat while’ loop allows you to continue looping some code until a condition is met. The empty socket next to the while loop allows you to connect some Logic and construct a statement.
-
-![](/static/mb/blocks/lessons/loops-1.png)
-
-The code above will scroll the message, “Press it!”, while the user hasn’t pressed the button.
-
-* Drag a `set item` block from the **Variables** drawer. Click the **down arrow** and click **New Variable**, and type "pressed". Drag a `0` block from **Maths** to set the variable **pressed** to 0.
-* Drag a `repeat while` block from the **Loops** drawer and attach an `=` block from the **Logic** drawer. Drag `item` from the **Variables** drawer and click the **down arrow**, select ‘pressed’. Drag a `0` block from Maths and connect it to the other side of the equals. This will carry out the code until ‘pressed’ does not equal 0.
-* Add a `show string` block from the **Basic** drawer and change the message to "Press it!"
-* Add an `if` block from the **Logic** drawer, connect a `button pressed` block from the **Input** drawer, and add text from the **Basic** drawer. Change this to A to show we are waiting for button A.
-* Inside the ‘do’ part of the if statement, add a `set` block from the Variables drawer, click the **down arrow** to change it to **pressed** and drag a `1` from the Maths drawer
-* Lastly underneath the while loop, add another `show string` block and fill in the gaps.
-
-Test the code above on actual hardware or on the simulator window.
-
-We can also change the code in subtle ways to have a completely different effect:
-
-![](/static/mb/blocks/lessons/loops-2.png)
-
-This time we have to press the button three times to leave the while loop.
-
-## Tip
-
-You can press the arrow next to a word in a block to change it. For example, you can change Math functions or change a Logic statement.
-
-### Count or for loops
-
-A count loop allows you to loop a certain amount of times and to change a variable as you do so. For example, we can create a simple counting program:
-
-![](/static/mb/blocks/lessons/loops-3.png)
-
-The count loop will repeat a certain amount of times whilst changing a variable. You can click the arrow next to **i** to replace it with any of your own variables. So this program will display numbers 1 to 10.
-
-This loop allows you to repeat code for the amount of times you want to without worrying about manually changing variables. You could use this for a counting program or a timer.

-# Game Library
-
-The game library supports simple single-player time-based games. The player has a **sprite**, number of **lives** and a **score**. The game has a sprite, number of **levels** and a **countdown clock**.  The general goal of a game will be to move the sprite and achieve a top score before time runs out or the number of lives goes to zero.
