Most of the “dangers” associated with using break or continue in a for loop are negated if you write tidy, easily-readable loops. If the body of your loop spans several screen lengths and has multiple nested sub-blocks, yes, you could easily forget that some code won’t be executed after the break.

Why is using break bad?

Use of the break statement is discouraged. Basically, this is because it allows you to exit the loop in more than one way (the normal exit, plus any conditions that cause a break ), which can be confusing; and it means that you may have to write additional code, after the loop, to figure out what the loop did.
