The nice thing about taking this course is that I do learn about tools and frameworks and libraries that I wouldn’t ordinarily encounter at work. This course is offered by Udemy. I have taken a few of their courses now and I am pleased with the value for the price. Still watch Lynda.com courses on a regular basis also (and they are the most valuable for my professional needs). Just recently found another course [from Harvard] that you may want to investigate on bits!
