Console Normalizer
==================

IE, oh IE, how we fight... this utility fixes issues with IE&#39;s console object so you can use it just like a real console.

Usage
-----

```html
    <script src="normalizeconsole.min.js"></script>
    <script>
        console.group('Play around');
        console.time('timer');

console.log('hello'); // does not blow up if IE console is closed

console.log.apply(console, ['one', 'two', 'three']); // does not cause an Invocation error

typeof(console.log); // function (some things you shouldn't have to say...)

console.info();
        console.warn();
        console.error();

console.timeEnd('timer');
        console.groupEnd();
    </script>
```

What it fixes
-------------

IE 8 & 9's console objects are a bit... well, it's IE, our favorite stepchild. To be fair, Chrome has a few similar issues which are fixed by this utility as well. Here's a quick summary, with details below:

* window.console available in IE, even if it is closed
 * console.log/info/warn/error.apply work in IE and Chrome
 * console.time and console.timeEnd supported
 * console.group and console.groupEnd supported
 * Function.prototype.bind added if it doesn't exist (for IE 8)

### console is null or not an object

The `window.console` object is only availble in IE 8/9 when it is opened; this is also true in Chrome.

### console.group and console.groupEnd

Implements compatible functions for `group` and `groupEnd`

### console.time and console.timeEnd

Implements compatible functions for `time` and `timeEnd`

### Function.prototype.apply

Calling `apply` on any of the logging methods (i.e. `console.log.apply(console, arguments)`) breaks with "Object doesn't support this property or method" in IE8  and a Method Invocation Error in IE 9. This is [because it is a "host object" and does not extend Object](http://stackoverflow.com/questions/5538972/console-log-apply-not-working-in-ie9).

### Function.prototype.bind in IE 8

As a side effect, this utility also implements a compatible version of Function.prototype.bind for IE 8.

Compatibility
-------------

Compatible with everything after IE 5.5
