Prerequisites: [Node.js](https://nodejs.org/) (`^12.22.0`, `^14.17.0`, or `>=16.0.0`) built with SSL support. (If you are using an official Node.js distribution, SSL is always built in.)

./node_modules/.bin/eslint yourfile.js

After running `npm init @eslint/config`, you'll have a `.eslintrc` file in your directory. In it, you'll see some rules configured like this:

The three error levels allow you fine-grained control over how ESLint applies rules (for more configuration options and details, see the [configuration docs](https://eslint.org/docs/user-guide/configuring)).

ESLint adheres to the [JS Foundation Code of Conduct](https://eslint.org/conduct).

We have scheduled releases every two weeks on Friday or Saturday. You can follow a [release issue](https://github.com/eslint/eslint/issues?q=is%3Aopen+is%3Aissue+label%3Arelease) for updates about the scheduling of any particular release.

ESLint takes security seriously. We work hard to ensure that ESLint is safe for everyone and that security issues are addressed quickly and responsibly. Read the full [security policy](https://github.com/eslint/.github/blob/master/SECURITY.md).

ESLint follows [semantic versioning](https://semver.org). However, due to the nature of ESLint as a code quality tool, it's not always clear when a minor or major version bump occurs. To help clarify this for everyone, we've defined the following semantic versioning policy for ESLint:

According to our policy, any minor update may report more linting errors than the previous release (ex: from a bug fix). As such, we recommend using the tilde (`~`) in `package.json` e.g. `"eslint": "~3.1.0"` to guarantee the results of your builds.

Stylistic rules are frozen according to [our policy](https://eslint.org/blog/2020/05/changes-to-rules-policies) on how we evaluate new rules and rule changes.

This means:

* **New ECMAScript features**: We will also make sure stylistic rules are compatible with new ECMAScript features.

* **New options**: We will **not** add any new options to stylistic rules unless an option is the only way to fix a bug or support a newly-added ECMAScript feature.
