About this Course
What you'll learn
The most common action you'll need to do with arrays is to look through each of its items. This is called iteration. Let's compare two approaches to iteration: for loops and the forEach method. Then we'll take a closer look at the forEach method.
Learn the most common iteration methods: filter, map and reduce. Each one is a tool in your belt, and you'll see when and how to use each one.
Combining Array Methods
Array methods can be chained together to give you even more power in working with array data. Learn how to combine filter, map and reduce in different ways to tackle common programming problems.
