Chapter 3. Introducing Functions: Getting functional

Image

Get ready for your first superpower. You’ve got some programming under your belt; now it’s time to really move things along with functions. Functions give you the power to write code that can be applied to all sorts of different circumstances, code that can be reused over and over, code that is much more manageable, code that can be abstracted away and given a simple name so you can forget all the complexity and get on with the important stuff. You’re going to find not only that functions are your gateway from scripter to programmer, but that they’re the key to the JavaScript programming style. In this chapter, we’re going to start with the basics—the mechanics, the ins and outs of how functions really work—and then you’ll keep honing your function skills throughout the rest of the book. So, let’s get a good foundation started, now.
