WebStorm is the best IDE hands-down for JavaScript developers. Yes, there's more lightweight editors (and nothing beats vim when debugging remotely), but the sheer productivity of WebStorm is unparalleled. React/JSX support? Check. ES2015 support? You bet. Node.js profiling? Yes! Look, if you can't rename a class or variable reliably across a JavaScript project, follow references, debug (without console logs) your editor sucks. Don't use a editor that sucks, use WebStorm! WebStorm
