# Break
Break statement; exit a for or while loop.
### @parent javascript/language
Exit a [while](/javascript/while) or [for](/reference/loops/for) loop before the loop is complete.
### Touch Develop syntax
**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)
}
}
```
