Chromium query.

If you provide it with a major Chromium version, it will return a major Electron version:

```js
var electronVersion = e2c.chromiumToElectron('54');
// electronVersion is "1.4"
```

If you provide it with a full Chrome version, it will return an array of full Electron versions.

```js
var electronVersions = e2c.chromiumToElectron('56.0.2924.87');
// electronVersions is ["1.6.3", "1.6.2", "1.6.1", "1.6.0"]
```

If a query does not match an Electron version, it will return `undefined`.

```js
var electronVersion = e2c.chromiumToElectron('10');
// electronVersion is undefined
```

#### `electronToBrowserList(query)` **DEPRECATED**
Arguments:
* Query: string or number, required. A major Electron version.

_**Deprecated**: Browserlist already includes electron-to-chromium._

A function that returns a [Browserslist](https://github.com/ai/browserslist) query that matches the given major Electron version. Returns a string.

If you provide it with a major Electron version, it will return a Browserlist query string that matches the Chromium capabilities:

```js
var query = e2c.electronToBrowserList('1.4');
// query is "Chrome >= 53"
```

If a query does not match a Chromium version, it will return `undefined`.

```js
var query = e2c.electronToBrowserList('9000');
// query is undefined
```

### Importing just versions, fullVersions, chromiumVersions and fullChromiumVersions
All lists can be imported on their own, if file size is a concern.

#### `versions`

```js
var versions = require('electron-to-chromium/versions');
```

#### `fullVersions`

```js
var fullVersions = require('electron-to-chromium/full-versions');
```

#### `chromiumVersions`

```js
var chromiumVersions = require('electron-to-chromium/chromium-versions');
```

#### `fullChromiumVersions`

```js
var fullChromiumVersions = require('electron-to-chromium/full-chromium-versions');
```

## Updating
This package will be updated with each new Electron release.

To update the list, run `npm run build.js`. Requires internet access as it downloads from the canonical list of Electron versions.

To verify correct behaviour, run `npm test`.
