JavaScript Functions
A function in JavaScript is similar to a procedure, a set of statements that performs a task or calculates a value. The way I look at functions is I see them as code snippets that you can call whenever you need to by name and as many times as you need to. So for example, you might have a function that you will name, let's just say we're going to call the function add numbers and add numbers.
