The break statement can also be used to jump out of a loop:

JavaScript Labels

To label JavaScript statements you precede the statements with a label name and a colon:

label:
statements

Syntax:

The continue statement (with or without a label reference) can only be used to skip one loop iteration.

The break statement, without a label reference, can only be used to jump out of a loop or a switch.

With a label reference, the break statement can be used to jump out of any code block:

A code block is a block of code between { and }.
