The config to share target browsers and Node.js versions between different
front-end tools. It is used in:

- [Autoprefixer]
- [Babel]
- [postcss-preset-env]
- [eslint-plugin-compat]
- [stylelint-no-unsupported-browser-features]
- [postcss-normalize]
- [obsolete-webpack-plugin]

All tools will find target browsers automatically,
when you add the following to `package.json`:

```json
  "browserslist": [
    "defaults and fully supports es6-module",
    "maintained node versions"
  ]
```

Or in `.browserslistrc` config:

```yaml
# Browsers that we support

defaults and fully supports es6-module
maintained node versions
```

Developers set their version lists using queries like `last 2 versions`
to be free from updating versions manually.
Browserslist will use [`caniuse-lite`] with [Can I Use] data for this queries.

You can check how config works at our playground: [`browsersl.ist`](https://browsersl.ist/)
