I did learn React from 2 years ago when it was hard to find any guide or tutorials on React. I had to dig the docs and repeated coding with trial-and-error learning style. It cost me quite a time to get familiar with because at that time I was working with Angular 1.x which is different from React. https://medium.com/@petehouston/how-i-learned-react-from-ground-up-or-how-to-get-started-with-react-development-with-care-491dfeff05a2#.nrmf1opbp
