Learn how to extract portions of a JavaScript array; how to join arrays together; how to convert an array to a string; and how to add and remove elements from an array.

Our first tutorial on JavaScript arrays covered the basics: creating arrays, accessing the contents of arrays, array lengths, and looping through arrays.
