What is the difference between iterators and generators in JavaScript?

What is the difference between iterators and generators in JavaScript?

Iterators are objects that allow you to traverse through a collection, while generators are a special type of iterator that can pause and resume execution.

Can you give me an example of an iterator?

Sure! An example of an iterator is the Array.prototype.values() method, which returns an iterator object that contains the values for each index in the array.

And how do generators work?

Generators are defined using the function* syntax and use the yield keyword to produce a value and pause execution. You can resume it later.

What are the benefits of using generators over regular iterators?

Generators are more concise and easier to read. They also allow for lazy evaluation, which can improve performance when dealing with large data sets.
