Filters … Not Just for Coffee: Part 1 of the Code Fellows “Mastering Arrays” Video Series

JavaScript’s array .filter() method for arrays makes the task of combing through arrays, even complex ones, very achievable.

Master this superhero of a method and enjoy a new level of readability in your code, while allowing you to help your users to consume large amounts of data in more concise, logical chunks.

How do I use it?

Let’s see it in action!
