How do I use a for-of loop with iterators in JavaScript?

How do I use a for-of loop with iterators in JavaScript?

You can use a for-of loop to iterate over iterable objects like arrays, strings, and more. For example:

const array = [1, 2, 3];
for (const value of array) {
    console.log(value);
}

Can you explain what an iterator is?

An iterator is an object that defines a sequence and potentially a return value upon its completion. It has a next() method that returns the next value in the sequence.

How does the for-of loop differ from a forEach method?

The for-of loop can be used with any iterable, while forEach is specifically for arrays. Also, for-of allows you to use break and continue, which forEach does not.

Can I use for-of with a Map or Set?

Yes, you can! Both Map and Set are iterable, so you can use for-of to iterate over their values or entries.
