In this video we'll learn how to perform common add and remove array operations such as append, prepend, insert, and remove. We'll look at the dangers of mutation that can be caused by using mutative array methods such as [Array.prototype.push]( and learn how to instead leverage non-mutative array methods such as [Array.prototype.concat]( and [Array.prototype.slice]( when working with arrays.
