Make Use of Array Methods

Arrays are one of the most used data structures in programming. Along with Math methods, JavaScript also provides several built-in array methods like push(), concat(), join(), forEach(), map(), sort(), and so on. You can make use of all these built-in methods to work comfortably with JavaScript arrays.
