When you’re learning javascript, you rarely get time to really dig into the more complex aspects of the language. Until now! This hybrid course mixes learning and hands-on practice with interactive coding challenges. Instructor Morten Rand-Hendriksen guides you through five advanced topics in javascript development: turning flat arrays into nested arrays, extending classes, using singletons and proxies, creating observable objects, and building robust applications with the reactive object pattern. Each chapter presents you with a basic introduction, two hands-on examples, and two coding challenges to solidify your learning. Advancing your skills in javascript means pushing yourself to go beyond the basics, and Morten shows you how to get it right.
