What's the ReSharper of the JavaScript/TypeScript world? Looking for something that offers refactoring capabilities and not just linting (ESLint etc).

Webstorm ?

Usually this is handled by tooling + extension where you can combine ESLint with Prettier to do formatting and basic lint cleanup for you without needing Webstorm (which is paid IDE).

The company that makes Resharper makes Webstorm & Pycharm

Thanks all, will give webstorm a try.
