A JavaScript equivalent of PHP's sizeof

{% codeblock array/sizeof.js lang:js https://raw.github.com/kvz/phpjs/master/functions/array/sizeof.js raw on github %}
function sizeof (mixed_var, mode) {
  // From: http://phpjs.org/functions
  // +   original by: Philip Peterson
  // -    depends on: count
  // *     example 1: sizeof([[0,0],[0,-4]], 'COUNT_RECURSIVE');
  // *     returns 1: 6
  // *     example 2: sizeof({'one' : [1,2,3,4,5]}, 'COUNT_RECURSIVE');
  // *     returns 2: 6
  return this.count(mixed_var, mode);

Please note that php.js uses JavaScript objects as substitutes for PHP arrays, they are 
the closest match to this hashtable-like data structure. 

Please also note that php.js offers community built functions and goes by the 
[McDonald's Theory](https://medium.com/what-i-learned-building/9216e1c9da7d). We'll put online 
functions that are far from perfect, in the hopes to spark better contributions. 
Do you have one? Then please just:

### Example 1
This code
{% codeblock lang:js example %}
sizeof([[0,0],[0,-4]], 'COUNT_RECURSIVE');
{% endcodeblock %}

Should return
{% codeblock lang:js returns %}
6
{% endcodeblock %}

### Example 2
This code
{% codeblock lang:js example %}
sizeof({'one' : [1,2,3,4,5]}, 'COUNT_RECURSIVE');
{% endcodeblock %}

Should return
{% codeblock lang:js returns %}
6
{% endcodeblock %}
