The Learn Enough series teaches you the developer tools, Web technologies, and programming skills needed to launch your own applications, get a job as a programmer, and maybe even start a company of your own. Along the way, you'll learn technical sophistication, which is the ability to solve technical problems yourself. And Learn Enough always focuses on the most important parts of each subject, so you don’t have to learn everything to get started—you just have to learn enough to be dangerous. The Learn Enough series includes books and video courses so you get to choose the learning style that works best for you.
