JSHint, A Static Code Analysis Tool for JavaScript

Build Status

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

Our goal is to help JavaScript developers write complex programs without worrying about typos and language gotchas.

We believe that static code analysis programs—as well as other code quality tools—are important and beneficial to the JavaScript community and, thus, should not alienate their users.

JSHint Fundraiser / Bug Bounties

We're running a fundraiser for JSHint! If JSHint helps you in your day-to-day development, please consider donating. All money raised on this page will be used as monetary rewards for fixing JSHint bugs and implementing new features. Our hope is to introduce more developers to JSHint hacking and boost its development.


  1. All funds (aside from fees) will be used only to fund bounties.
  2. If core team ends up fixing bounty bugs, the reward will be donated to the Electronic Frontier Foundation.
  3. Before marking bugs as fixed, all patches must be reviewed by a core team member.


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.


How do I turn off "mixed tabs and spaces" warning?

If you're using so-called smart tabs then we have an option smarttabs for you. Otherwise, your solution is to run JSHint with a custom reporter that discards any warnings you don't like. For example, this example reporter discards all warnings about mixed tabs and spaces.


Look for a file named CONTRIBUTING.md in this repository. It contains our contributing guidelines. We also have a mailing list.
