What are Map iterators in JavaScript ES6?

Can you explain what Map iterators are in JavaScript ES6?

Sure! Map iterators in JavaScript ES6 allow you to iterate over the keys, values, or entries of a Map object. They provide methods like keys(), values(), and entries().

How do I use the forEach method with a Map?

You can use the forEach method directly on a Map. It takes a callback function that receives the value, key, and the Map itself as arguments. Here's an example: myMap.forEach((value, key) => { console.log(key, value); });

What is the difference between keys() and entries()?

The keys() method returns an iterator for the keys of the Map, while entries() returns an iterator for both keys and values as an array of [key, value] pairs.

Can I convert a Map to an array?

Yes, you can convert a Map to an array using the Array.from() method or the spread operator. For example: const arr = Array.from(myMap); or const arr = [...myMap];.
