The break statement exits a switch statement or a loop (for, for ... in, while, do ... while).

When the break statement is used with a switch statement, it breaks out of the switch block. This will stop the execution of more execution of code and/or case testing inside the block.

When the break statement is used in a loop, it breaks the loop and continues executing the code after the loop (if any).

The break statement can also be used with an optional label reference, to "jump out" of any JavaScript code block (see "More Examples" below).

Note: Without a label reference, the break statement can only be used inside a loop or a switch.

Example

In this example we use a for loop together with the break statement.

Loop through a block of code, but exit the loop when the variable i is equal to "3":

var text = ""
var i;
for (i = 0; i < 5; i++) {
  if (i === 3) {
    break;
  }
  text += "The number is " + i + "<br>";
}
