Use the full power of the modern javascript ecosystem - WebStorm's got you covered! Enjoy the intelligent code completion, on-the-fly error detection, powerful navigation and refactoring for javascript, TypeScript, stylesheet languages, and the most popular frameworks.

Debugger
Debug your client-side and Node.js apps with ease in the IDE - put breakpoints right in the source code, explore the call stack and variables, set watches, and use the interactive console.

Seamless tool integration
Take advantage of linters, build tools, test runners, REST client, and more tools, all deeply integrated with the IDE. But any time you need Terminal, it's also available as an IDE tool window.

Unit testing
Run and debug tests with Karma, Mocha, Protractor, and Jest in WebStorm. Immediately see test statuses right in the editor, or in a handy treeview from which you can quickly jump to the test.

Integration with VCS
Use a simple unified UI to work with Git, GitHub, Mercurial, and other VCS. Commit files, review changes and resolve conflicts with a visual diff/merge tool right in the IDE.
