This chapter will focus on working with JavaScript arrays. As a JavaScript developer, you will use the array often; it is the most commonly used data structure. Arrays in JavaScript come with a lot of built-in methods. In fact, there are various ways to do the same type of array operations for each use case. By the end of this chapter, you will understand how to work with arrays and be able to choose the right method for the situation.
