debugging is the best I've ever experienced. Webstorm debugging was problematic for me a year and a half ago. Visual Code has surpassed Atom by far as well, which weirdly does NOT support client side debugging for javascript (and that's a major mistake on Atom's behalf). In VSCode debugging is of course provided by 3rd party packages, but their API and rich debugging GUI seems to make it extremely easy to hook into it. In short, if you're using webpack-generated sourcemaps, VSCode is the way to go. Being able to finally debug in your actual code (rather than Chrome devtools) is a dream come true! Otherwise I love their built-in linting and git support.

Here's the chrome debugger:

I've submitted several bug reports to its creator (a developer at Microsoft) and received prompt response as well as fixes! It lets you attach to running browser windows or launch a new one.

Next and perhaps more importantly, there's a debugger for React Native!:

And it works flawlessly, and brings along IntelliSense for React Native elements/apis, etc.

If you're a javascript developer, drop what you're doing / what you're using, and make the shift to VSCode. If you're using Atom currently, you can likely find your same themes in the VSCode extension directory, which--for me--made the shift almost seamless (the feel shares a lot in common with Atom because of its Electron roots).
