JSHint, A Static Code Analysis Tool for JavaScript

[ Use it onlineAboutDocsFAQInstallHackBlogTwitter ]

Build Status NPM version

JSHint is a community-driven tool to detect errors and potential problems in JavaScript code. It is very flexible so you can easily adjust it to your particular coding guidelines and the environment you expect your code to execute in.

JSHint 2.x versus JSHint 3

There's an effort going on to release the next major version of JSHint. All development in the master branch is for the version 3.0. Current stable version is in the 2.x branch. Keep that in mind when submitting pull requests.

Also, before reporting a bug or thinking about hacking on JSHint, read this: JSHint 3 plans. TL;DR: we're moving away from style checks within JSHint so no new features around style checks will be accepted. Bug fixes are fine for the 2.x branch.

Reporting a bug

To report a bug simply create a new GitHub Issue and describe your problem or suggestion. We welcome all kind of feedback regarding JSHint including but not limited to:

  • When JSHint doesn't work as expected
  • When JSHint complains about valid JavaScript code that works in all browsers
  • When you simply want a new option or feature

Before reporting a bug look around to see if there are any open or closed tickets that cover your issue. And remember the wisdom: pull request > bug report > tweet.
