TIL Labels in Javascript

The labeled statement can be used with break or continue statements. It is prefixing a statement with an identifier which you can refer to.

How does it work?

fireThisStatement: {
  console.log("first");
  break fireThisStatement;
  console.log("second");
}

// > first
// -> undefined

TYou can use a label to identify a loop, and then use the break or continue statements to indicate whether a program should interrupt the loop or continue its execution.

In the example above, we identify a label fireThisStatement. After that console.log('first'); executes and then we interrupt the execution.
