break Keyword

The break statement includes an optional label that allows the program to break out of a labeled statement. The break statement needs to be nested within the referenced label. The labeled statement can be any block statement; it does not have to be preceded by a loop statement.

A break statement, with or without a following label, cannot be used within the body of a function that is itself nested within the current loop, switch, or label statement that the break statement is intended to break out of.
