# globals [](https://travis-ci.org/sindresorhus/globals)
> Global identifiers from different JavaScript environments
Extracted from [JSHint](https://github.com/jshint/jshint/blob/master/src/vars.js) and [ESLint](https://github.com/nzakas/eslint/blob/master/conf/environments.json) and merged.
It's just a [JSON file](globals.json), so use it in whatever environment you like.
## Install
```
$ npm install --save globals
```
## Usage
```js
var globals = require('globals');
console.log(globals.browser);
/*
{
addEventListener: false,
applicationCache: false,
ArrayBuffer: false,
atob: false,
...
}
*/
```
Each global is given a value of `true` or `false`. A value of `true` indicates that the variable may be overwritten. A value of `false` indicates that the variable should be considered read-only. This information is used by static analysis tools to flag incorrect behavior. We assume all variables should be `false` unless we hear otherwise.
