.forEach iteration method is a kind of undefined return value?

[weiqhyeah]

What does it mean when it says .forEach returns undefined?

Is it the SCT that is giving your that message, or is it a console error? I’m not able to reproduce this issue.

Hey! May I have your name? You helped me out a lot. But I don’t know how to call you.
I got confused as the this girl about .forEach iteration method is a kind of undefined return value.

Array.prototype.forEach() - JavaScript | MDN

It is also named as undefined in MDN.

Thank you so much for always answering my questions.

The forEach method has no return, and it also has no break. For this reason it should not be logged, as in,

console.log(array.forEach(function () {}));
