The JavaScript Specialist v2.0 course contains rich contents. It started from JavaScript introduction, and comprehensively explained every aspect of the programming language including Variables and Data types, functions, methods, events, control flow, JavaScript DOM, Objects, Hoisting, Closures and more. It teaches modern JavaScript having examples and code snippets written in ES6 standard.

I was impressed going through the CIW JavaScript course, it was really great and comprehensive; a nice blend of videos and text. Every lesson has short videos that introduce the concepts and a more in-depth note that covers more intricate areas of the language. You also get quizzes in-between to test your understanding of the concepts just covered with very interactive flashcards.

The uCertify JavaScript study guide contains vocabularies, which has digital index cards and you can flip over for definitions. You can also watch videos for understanding the basics, and the text is pretty high in dense, so there's a lot you can learn from. And it's all in easy English, nothing complicated like some of the books you'll find out there.
