What is the difference between assert and break keywords?

Answer 1

This is what i found for your question:

ASSERT: Assert statements are a convenient way to insert debugging assertions into a program.
BREAK: It terminates the current loop and resumes execution at the next statement.

Answer 2

one more difference i found is that
assert keyword can be written outside the loop but it is not so with the break keyword.
break keyword if written outside the loop gives error.
