Does the ForEach loop allow using break and continue?

Question

Does the ForEach loop allow us to use break and continue?

I\'ve tried using both but I received an error:

Illegal          


        

Answer 1

As already answered, you cannot use continue or break inside a JavaScript Array.prototype.forEach loop. However, there are other options:

Option 1

Use the jQuery .each() function (Reference).

Simply return true to continue, or return false to break the loop.

Option 2

Just use return to continue or throw new Error() to break. I don't necessarily recommend doing it this way, but it's interesting to know that this is possible.

try {
    [1, 2, 3, 4].forEach(function(i) {

        if (i === 2) {
            return; // continue
        }

        if (i === 3) {
            throw new Error(); // break
        }

        console.log(i);
    });
}
catch (e) {
}

The expected result is just 1
