What are common iterable objects in JavaScript?

Common iterable objects in JavaScript include Arrays, Strings, Maps, Sets, and NodeLists.

Can you explain how to use a Set as an iterable?

Sure! A Set can be iterated using the for...of loop. For example: let mySet = new Set([1, 2, 3]); for (let item of mySet) { console.log(item); }.

What about Maps? How do they work as iterables?

Maps are also iterable. You can use forEach or for...of. For example: let myMap = new Map([[1, 'one'], [2, 'two']]); myMap.forEach((value, key) => { console.log(key, value); });.

Are there any other iterable objects I should know about?

Yes, NodeLists from DOM queries are iterable too. You can loop through them like arrays.
