In this chapter, we covered the most-used data structure: arrays. You learned how to declare, initialize, and assign values as well as add and remove elements. You also learned about two-dimensional and multidimensional arrays as well as the main methods of an array, which will be very useful when we start creating our own algorithms in later chapters.
You also learned the new methods and functionalities that were added to the Array
class in the ECMAScript 2015 and 2016 specifications.
In the next chapter, you will learn about stacks, which are arrays with a special behavior.
