break

Example: count to a random number

The following example counts from 0 to a random number from 0-9. When the for loop counter equals the random number (i = x), the break statement exits the loop:

let x = Math.random(10)
for (let i = 0; i < 10; i++) {
    if (i == x) {
        break
    } else {
        basic.showNumber(i, 0)
        basic.pause(500)
    }
}
