How to Use JavaScript Arrays - Crash Course [Video]

lincolnwdaniel profile image Lincoln W Daniel ・1 min read

In this video, we take a crash course on how to use JavaScript arrays to store a list of items, access individual items of an array by their index, and loop through an array to access all or some of the elements of an array. We end by learning how to manipulate an array to change a specific element at an index, push items onto an array, and remove items from an array in JavaScript.

Storing data is an important part of programming; accessing that data is also important. In many cases, you'll have to store data as a list, array for the sake of efficiency when accessing, transferring, and manipulating that data later in your program.
