What is the use of the Break Statement in a Loop in JavaScript ?
The break
statement in JavaScript is used to prematurely terminate a loop, allowing the program to exit the loop before the normal loop condition is met. It is often used to interrupt the loop execution based on certain conditions.
Example: Here, the while
loop will continue indefinitely (since the condition is true
). However, the if
statement inside the loop checks if the counter
is equal to 3. When this condition is met, the break
statement is executed, causing the loop to terminate immediately.
Javascript
let counter = 1; while ( true ) { console.log(counter); if (counter === 3) { console.log( "Breaking out of the loop." ); break ; } counter++; } |
Output
1 2 3 Breaking out of the loop.
