### Challenge 0
|
|
|
|
Welcome! This [guided tutorial](/lessons/return/tutorial) will help you code the following script!
|
|
|
|
```
|
|
let original1 = 5
|
|
input.onButtonPressed(Button.A, () => {
|
|
let doubled = doubleIt_(5)
|
|
basic.showNumber(doubled, 150) // ***
|
|
})
|
|
```
|
|
|
|
### Challenge 1
|
|
|
|
Create a new function called `square` that returns squares the number passed into the function. (Squaring means that you multiply the number by itself.)
|
|
|
|
```
|
|
export function squareIt(n: number) : number {
|
|
let num: number
|
|
return n * n
|
|
return num
|
|
}
|
|
```
|
|
|
|
### Challenge 2
|
|
|
|
Add a condition to know when button `B` is pressed. We will use this condition in the last challenge.
|
|
|
|
```
|
|
let original = 5
|
|
input.onButtonPressed(Button.A, () => {
|
|
let one = doubleIt_(original)
|
|
basic.showNumber(one, 150)
|
|
})
|
|
input.onButtonPressed(Button.B, () => {
|
|
})
|
|
```
|
|
|
|
### Challenge 3
|
|
|
|
When the `B` button is pressed, display the square of the original value. Use the function `square it`. You should get the value 25.
