I know I'm struggling with modern JavaScript tooling. I've been using React with JSX and maybe as little as React router too. Trying to get router added was so painful. NPM, Babel, we pack, grunt, gulp, etc and then you find you've been given instructions for something on an old react version and you need different tooling for a new one. Or the instructions give you something that's really only suitable in dev not production. I actually gave up trying to add Flux and wrote my own implementation in vanilla JS which seems ludicrous to me.
