Task: Using helper liberaries

← Previous task Next task →

Information

In the examples we have seen so far, we have used methods that live on an array. We are now going to switch tactics and focus more on functions instead of methods. For example, in addition to Array.prototype.reduce, there exists a reduce functions in libraries such as Lo-Dash and Underscore. One of the primary values of using these functions instead is composability. We are going to look more on what exactly that means later. Another great thing is that some of these functions are more powerful that the methods on arrays.

In this course we will use Lo-Dash, which will be accessible through the _ global (however, we could also have chosen Underscore instead).
