The 'break' statement is a statement that allows you to terminate the execution of a loop or a switch statement.

The syntax of a 'break' statement in JavaScript is 'break;', where ';' is the statement terminator.

The 'continue' statement is a statement that allows you to skip the current iteration of a loop and continue with the next iteration.
