It's painful coming from the sane and stable ecosystem of backend dev, but investing time into learning JS is very much worth it both for your product, and your career. For a solid foundation in ES5 (still worth learning well IMO), I would recommend: Secrets of the JavaScript Ninja Javascript the good parts Cozy up to MDN documentation, and get familiar w/ jQuery after learning the basics of DOM manipulation using the browser API. Lots of people will tell you to learn ES6/ES7/webpack/babel/npm/angular/ember/react/redux/etc (FML just typing this list) but at the end of the day, you will get plenty far with ES5 and Bootstrap taking care of the CSS. More than enough to earn some serious bucks (if your product isn't terrible). jQuery and plugins will take you far. Once making serious cash, hire/outsource if you feel you need for something more advanced and polished.
