In this walkthrough, we look at, How to Choose the Right Iterator, and Choosing right Iterators with JavaScript on Codecademy's Learn JS. In this video, we go over the Codecademy lesson, "Choose the Right Iterator", from their Learn JavaScript course's Iterator section. This lesson tests our JavaScript knowledge. It goes over iterators we just learned and has us apply them in different scenarios. We go over the following JavaScript iterators: forEach() method, filter() method, reduce() method, .map() method, and .some() method. It is important to understand the difference between each method and the importance of applying them in the right context. Learning to master iterators in programming is key in mastering programming concepts and getting closer to fully understanding how programming languages operate!
