+# global-object
+
+There are at least 3 different ways to reference the global object mentioned in ES6/2015
+
+  * `window` historically on HTML pages
+  * `self` in Workers, and historically on HTML pages too
+  * `global` in basically all server side implementation of JavaScript
+
+If we search in Github, the summed amount of `typeof window` or `typeof global` checks,
+mostly to understand which one is available, is about 23 millions of times.
+
+This is madness, and since there's no reason at all to prefer anything different from `global`
+for an object defined indeed as the global object in the global scope, I've decided to create
+this page in order to put an end to all this.
+

+
+Forget about `window` and `self` in Workers, normalize your work-flow once for all
+and with or without browserify in place!
+
+
+### As first script in your page
+This is the most straight forward way to have it defined everywhere as such
+```html
+<script>var global=global||this;</script>
+```
+No need to disturb the network, no need to ever update the script even if a browser
+will eventually expose `global` reference. It goes there to stay.
+
+
+### As first script in your Worker
+Same goes with Web Workers and others, the code is exactly the same, without the node:
+```html
+var global=global||this;
+```
+Forget about `self` or `typeof window` checks, we've got `global`!
+
+
+### As anything else
+ES6, node itself, whatever ... 
+```js
+// ES6
+import global from 'global-object';
+
+// npm require
+var global = require('global-object');
+
+// browser
+script.src = 'global-object.js';
+```
+Just use [global-object](global-object.js)
+
+
+### Strict compatible!
+Yes, the `this` reference in the global scope is always the global object.
+In HTML pages like in workers, it will work everywhere even after `"use strict"` directive!
+
+
+### Content Security Policy Compatible
+Using this meta will solve all problems:
+```html
+<meta http-equiv="Content-Security-Policy" content="script-src 'unsafe-inline' 'self' 'sha1-WWQNP0ydesPxK1yAm94nH5bQoIo=' 'sha256-5rMu52Es8MMWNrCqRkunbIAeVDz8iJ63wD0rPm57xi4='">
+```
+Great, no network request required, and `global` available under CSP too!
+
+
+### License
+Nope, nothing ... do what you want, literally!
