break statement การใช้

The break statement is used to end a for loop, while loop, do loop, or switch statement.
There is also a yield break statement, in which control is unconditionally returned to the caller of the iterator.
Syntactically, the cases are interpreted as labels, not blocks, and the switch and break statements explicitly change control flow.
The Break statement may optionally pass any type of expression, which may be accepted by the RECOVER statement to allow further recovery handing.
When such a loop is created intentionally, there is usually another control structure ( such as a break statement ) that allows termination of the loop.
