Exit a [while](/microbit/js/while) or [for](/microbit/reference/loops/for) loop before the loop is complete.

### 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)
|
|
}
|
|
}
|
|
```
