JavaScript Boot Camp

Abstract

JavaScript is one of the most predominant languages in use today. There is virtually no website that you can visit these days that does not leverage JavaScript to do anything from improve your experience with the site’s content to recording robust analytics about how you are using the site. JavaScript’s flexibility in allowing developers to choose a style of programming that best fits their style is one of its greatest assets (or, if you are a pessimist, one of its greatest faults), and engineers have put in a lot of work to squeeze every bit of optimization into their JavaScript engines to ensure this code executes as quickly as possible. This chapter introduces you to some of the important JavaScript concepts that we use throughout the rest of the book.
