4.18 JUMP STATEMENTS IN JAVASCRIPT
Sometimes, there is a situation when the control of the program needs to be transferred out of the loop body, even
if all the values of the iterations of the loop have not been completed. For this purpose, jump statements are used in
JavaScript. JavaScript offers two jump statements—break and continue.
You have already seen the use of break to exit the switch statement. You can also use the break statement to “jump
out” of a loop.
The break is a keyword in JavaScript which is used for bringing the program control out of the loop. The break statement
halts the execution of a loop and program flow switches to the statement after the loop. A single break statement will
break out of only one loop.
