In this article, we would like to show you break statement in JavaScript.

break [label];The break statement ends the current loop, switch, or label statement and proceeds to the statement following the ended statement.
In this example, we use break statement to terminate the while loop on the specific condition.

let i = 0;2

while (i < 5) {4
if (i === 2) {5
break;6
}7
i = i + 1;8
}9
10
console.log(i); // 2Note:
If the statement we want to break is not a loop or switch,
labelis required.
In this example, we use the break statement to terminate the switch statement when a case is matched and the corresponding code has been executed.
