Add eloquent js to javascript language node.

Hi there! This book has helped me greatly with learning javascript. It is so pleasant to read but highly detailed, eloquently written as the title suggests. The book includes exercises for every chapter, with solutions, multiple projects, and has everything available with its own code sandbox. I have the paperback copy, but I love having all of the extra features with the online version. It is 100% free.
