When button B is pressed, we want to clear the screen. This will make it so users can play your game over and over again! Add an event handler to handle this case.

input.onButtonPressed(Button.A, () => {
    let x1 = Math.random(10)
    basic.showNumber(x1, 150)
})
input.onButtonPressed(Button.B, () => {
    basic.clearScreen() // ***
})

Challenge 2

Show an animation when you clear the screen! Choose what animation makes most sense to you. Be creative!
