can-globals/is-browser-window/is-browser-window.js

This module provides a dependency injection container. Modules may define a key and specify a default value (which can be static, cached lazy, or dynamic lazy), but other code can set and reset the value as needed. There is also an event system, for alert

'use strict';

var globals = require('can-globals/can-globals-instance');

// This module depends on isNode being defined

/**
 * @module {function} can-globals/is-browser-window/is-browser-window is-browser-window
 * @parent can-globals/modules
 * @signature `isBrowserWindow()`
 *
 * Returns `true` if the code is running within a Browser window. Use this function if you need special code paths for when running in a Browser window, a Web Worker, or another environment (such as Node.js).
 *
 * ```js
 * var isBrowserWindow = require("can-globals/is-browser-window/is-browser-window");
 * var GLOBAL = require("can-globals/global/global");
 *
 * if(isBrowserWindow()) {
 *   console.log(GLOBAL() === window); // -> true
 * }
 * ```
 *
 * @return {Boolean} True if the environment is a Browser window.
