0x00 Lesson
If you put a loop inside a loop it’s called a nested
loop, and it’s not uncommon to want to break out of both the inner loop and the outer loop at the same time.
As an example, we could write some code to calculate the times tables from 1 through 10 like this:
If we wanted to exit part-way through we need to do two things. First, we give the outside loop a label. like this:
Second, add our condition inside the inner loop, then use break outerLoop
to exit both loops at the same time:
With a regular break
, only the inner
loop would be exited
- the outer
loop would continue
where it left off.
