Over one year ago, we [announced Hound support for JavaScript][js-support].
Behind the scenes, Hound linted JavaScript code with [JSHint][jshint].

In the past year, JSHint has deprecated several rules, stating:

> **Warning** This option has been deprecated and will be removed in the next
> major release of JSHint.
> JSHint is limiting its scope to issues of code correctness.
> If you would like to enforce rules relating to code style,
> [check out the JSCS project][jscs].

[jshint]: http://jshint.com/
[jscs]: http://jscs.info/

To support this shift in responsibilities, we're excited to announce
JavaScript Code Style (JSCS) support for Hound!

JSCS accepts over [150 configurable rules][rules] to support your team's
stylistic tastes.

Looking for a solid starting point? Extend your JSCS ruleset with [presets] from
popular open-source projects like [jQuery] or [WordPress],
or companies like [Airbnb] and [Google].

Migrating from [ESLint]? Use the [Crockford] preset!

[WordPress]: https://make.wordpress.org/core/handbook/coding-standards/javascript/

## Turn it on

JSCS linting is meant to work alongside our [JSHint linting][jshint-post].

You can enable or disable JSCS linting, or reference your own config,
by editing .hound.yml in your repo.

Example `.hound.yml`:

```yml
javascript:
  config_file: .jshintrc
jscs:
  enabled: true
  config_file: .jscsrc
```

Hound-JSCS's [current linter] supports [`jscs@^2.6.0`][jscs-2.6.0].

Unfortunately, we don't support [custom additional rules][custom] yet.

Like the rest of Hound's architecture, Hound's JSCS linter is also
[open-source]!

We think Hound is the best way to add style-checking to your workflow.
Since it’s free for open source projects, it couldn’t be easier to
[get started].
