Array manipulation, ordering, searching, summarizing, etc

Data in JavaScript is often represented by an array, and so one tends to manipulate arrays when visualizing or analyzing data. Some common forms of manipulation include taking a contiguous slice (subset) of an array, filtering an array using a predicate function, and mapping an array to a parallel set of values using a transform function.

Before looking at the set of utilities that this module provides, familiarize yourself with the powerful array methods built-in to JavaScript.

Node.js is an event-based server-side JavaScript engine.
