The answer
You place a boolean condition (like !stopAll) in the outer loop's condition block. The inner loop triggers the flag and breaks, causing the outer loop to evaluate the flag and terminate.

How does a boolean flag help break outer loops?

No, the break keyword only terminates the innermost loop in which it currently resides. Outer loops will continue executing.
The cleanest way is to wrap the logic in a function and use a 'return' statement, which completely bypasses all loops and exits the function instantly.
Supported in languages like Java and JS, a labeled break allows you to attach a name to an outer loop, so an inner break statement can target and terminate it explicitly.
