Overview

JSHint, A Static Code Analysis Tool for JavaScript

[ Use it online • Docs • FAQ • Install • Contribute • Blog • Twitter ]

JSHint is a community-driven tool that detects errors and potential problems in JavaScript code. Since JSHint is so flexible, you can easily adjust it in the environment you expect your code to execute. JSHint is publicly available and will always stay this way.

Our goal

The project aims to help JavaScript developers write complex programs without worrying about typos and language gotchas.

Any code base eventually becomes huge at some point, so simple mistakes — that would not show themselves when written — can become show stoppers and add extra hours of debugging. So, static code analysis tools come into play and help developers spot such problems. JSHint scans a program written in JavaScript and reports about commonly made mistakes and potential bugs. The potential problem could be a syntax error, a bug due to an implicit type conversion, a leaking variable, or something else entirely.

Only 15% of all programs linted on jshint.com pass the JSHint checks. In all other cases, JSHint finds some red flags that could've been bugs or potential problems.

Please note, that while static code analysis tools can spot many different kind of mistakes, it can't detect if your program is correct, fast or has memory leaks. You should always combine tools like JSHint with unit and functional tests as well as with code reviews.

Reporting a bug

To report a bug simply create a new GitHub Issue and describe your problem or suggestion. We welcome all kinds 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, please look around to see if there are any open or closed tickets that discuss your issue, and remember the wisdom: pull request > bug report > tweet.

Comments

Please change jshint.js license, remove bad or evil

Hi, could you please modify the jshint.js license to be a real MIT license?

The "The Software shall be used for Good, not Evil." prevents library to be packaged in Debian and maybe other repo where code should really be free of use (yes, even evil). And honestly, if someone wants to use it for evil... well I don't think he will care about the license :-)

Thanks

Option for switch case indentation

It would be great to have an option to customize how switch statements should be indented (i.e. whether to follow Java's style of case statements having same indentation as switch or allowing extra indentation for case statements)

switch (condition) {
case ABC:
    statements;
    break;
case DEF:
    statements;
    break;
default:
    statements;
    break;
}

vs.

switch (condition) {
    case ABC:
        statements;
        break;
    case DEF:
        statements;
        break;
    default:
        statements;
        break;
}

redefinition of Promise (W079)

I just switched from 2.4.4 to 2.5.1 But now all my requires are messed up because:

var Promise = require('bluebird') Will warn about: Redefinition of Promise (W079)

Is there anyway I can fix this ? I'm using bluebird all over the place.

Opt-out of `Confusing use of '!'.`

This check was added for issue #211 but there is no way to opt-out of this detection. As the original poster of that issue suggested, it should be enabled by default, but with an override.

Add QUnit support to the assume list

I was running JSHint on my tests and thought it would be nice to have an assume QUnit option just like you can for jQuery. Looking through the source, here is a suggestion.

under boolOptions add the qunit option

qunit      : true, // if QUnit globals should be predefined

define all the qunit functions (taken from http://docs.jquery.com/Qunit)

    qunit = {
        asyncTest      : false
        deepEqual      : false
        equal          : false
        expect         : false
        module         : false
        notDeepEqual   : false
        notEqual       : false
        notStrictEqual : false
        ok             : false
        QUnit          : false
        raises         : false
        start          : false
        stop           : false
        strictEqual    : false
        test           : false
    },

add support for qunit in assume()

    if (option.qunit)
        combine(predefined, qunit);

Update minimatch version
Could you please update your package to use the latest version of minimatch? The version currently used by jshint is throwing deprecation warnings:

High cyclomatic complexity on switch statements
Currently, every case in a switch block increments the cyclomatic complexity regardless of whether or not it falls through.

This has a complexity of 4:

function(someVal) { switch (someVal) { case 1: case 2: case 3: doSomething(); break; default: doSomethingElse(); break; } }

This has a complexity of 2 while being logically equivalent:

function(someVal) { if (someVal === 1 || someVal === 2 || someVal === 3) { doSomething(); } else { doSomethingElse(); } }

I'm not an expert in cyclomatic complexity by any means, so I'm honestly not sure if this is correct or not. Even if this is the expected behavior, it seems like it would be nice to at least have a flag which could make these two function calculate the same cyclomatic complexity.

Experimental Traceur features/ES7

One experimental/ES7 feature supported through Traceur that I want to start using today is async/await.

What is JSHint’s stance on supporting experimental Traceur features i.e. ES7, e.g. async/await?

option for making new optional
Most of the code I deal with makes use of new with constructors optional, neither it's used:

function Constructor() { var object = Object.create(Constructor.prototype) // .... return object } var object = Constructor()

JSHint always reports error on instantiation on last line. Would be nice to have an option to suppress reports on these.

Added optional asyncawait support on top of esnext.
Seems to work, passes the test suite, works well with arrow function and classes.

Configure like in the following:

"esnext": true "experimental": ["asyncawait"] or "experimental": ["asyncawait", "asyncreqawait"]

To try it:

npm install -g -f https://github.com/sebv/jshint/archive/esnextnext.tar.gz

EDIT updated options.

Option to assume strict mode (for nodejs)

Now that nodejs is es5 compliant it can be run in strict mode by default without including (function () { "use strict"; /* code here */ }());.

Will you add an option implicitstrict so that it's not required to have the boilerplate code?

Trying this in vscode:

if (x) /abc/.exec('abc'); while (x) /abc/.exec('abc'); for (;x;) /abc/.exec('abc'); if (false) ; else /abc/.exec('abc');

2.10.0 (2019-02-05)

This release introduces support for the three most recent editions of JavaScript: ES7, ES8, and ES9. Users can enable support for any one of these via the esversion linting option.

Perhaps most notably, this includes "async functions." Since their standardization in ES2017, no feature has been more requested. We're happy to add support for this powerful new language feature. If the delay is any indication, extending JSHint's parser was no small task, and we were able to make many seemingly-unrelated corrections along the way.

That progress is easiest to see in JSHint's performance on Test262 (the official test suite for the JavaScript programming language). Version 2.9.6 passed 84% of those tests. Version 2.10.0 passes 96%. We're excited to push that number higher, especially considering that new language features and new tests are being added every day. If you're curious about what needs to be done, we maintain an "expectations file" describing every test JSHint is known to fail today.

This release also includes brand-new parsing logic for classes. We thank Ethan Dorta and Alex Kritchevsky, the two first-time contributors who made this possible!

2.9.1(Jan 14, 2016)

2.9.1 (2016-01-14)

Following the revocation of version 2.9.0, we observed an extended "release candidate" phase where we encouraged users to vet JSHint for undesirable changes in behavior. During that time, we identified and resolved a number of such regressions. This release comprises all changes from the release candidate phase along with the improvements initially released as version 2.9.0. This release does not itself contain any changes to the codebase. If you are upgrading from version 2.8.0 or earlier, please refer to the previously-published release notes for details on bug fixes and features--these can be found in the project's CHANGELOG.md file and on the project's website.

2.9.1-rc1(Nov 12, 2015)
2.9.1-rc1 (2015-11-12)

Version 2.9.0 was revoked shortly after its release due to a number of regressions. Although the underlying issues have been resolved, we are sensitive to the possibility that there may be still more; as mentioned in 2.9.0's release notes, the variable tracking system saw a significant refactoring.

In an effort to minimize friction with a new version, we're publishing a release candidate and requesting feedback from early adopters. Please give it a try in your projects and let us know about any surprising behavior!
