  Super interactive course that spells most of the abstract parts of this language into an easy-to-digest manner. There's a lot of insight in the forum and I thought it was the most conducive to progress, as I found that some of my "classmates" were also having similar questions to mine.

  Each step of the course was clearly explained and the activities naturally deepened my understanding of each concept. I finished it feeling more confident in my knowledge of JavaScript than I have with other courses of similar content.
