In JavaScript, labels are identifiers that allow you to name blocks of code, such as loops and conditional statements. They are used in conjunction
with statements like break and continue to control the flow of execution within nested loops and conditionals.
It’s worth noting that labels are not widely used in modern JavaScript programming because they can lead to complex and hard-to-maintain code. In
most cases, there are better alternatives to achieve the desired control flow without resorting to labels.
myLabel: {
let x = doSomething();
if (x > 0) {
break myLabel;
}
doSomethingElse();
}
If you find yourself using labels, you should reevaluate your code structure and explore other options for better code clarity and
maintainability.
let x = doSomething();
if (x <= 0) {
doSomethingElse();
}
