Course details

Every JavaScript program you write will eventually have to make decisions and complete repetitive tasks. How good are you with conditionals and loops? How do you get better? Practice, practice, practice! But where to find it, and how to structure it? In this course, David Eisenberg gives you the chance to test your skills, find your focus, and work through problems that are just challenging enough to help you achieve the next level of JavaScript development. The course starts with an assessment quiz, so you can determine how much you already know about each topic, and whether you need to review or dive right into the challenges.
