Global identifiers from different JavaScript environments

Extracted from JSHint and ESLint and merged.

It's just a JSON file, so use it in whatever environment you like.

This module no longer accepts new environments. If you need it for ESLint, just create a plugin.

$ npm install globals

const 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.
