Just started looking at this one:<p><a href="http:&#x2F;&#x2F;www.freecodecamp.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.freecodecamp.com&#x2F;</a><p>Free coding camp.  Social code review. A certification that includes doing real projects for non-profits.  Even an interview prep at the end.  I am looking at it as a quick way to brush up on current front end dev.  They have HTML, CSS, JavaScript, React, D3, Node.js, etc, etc, etc.
