A JavaScript equivalent of PHP's pos

{% codeblock array/pos.js lang:js https://raw.github.com/kvz/phpjs/master/functions/array/pos.js raw on github %}
function pos (arr) {
  // From: http://phpjs.org/functions
  // +   original by: Brett Zamir (http://brett-zamir.me)
  // %        note 1: Uses global: php_js to store the array pointer
  // -    depends on: current
  // *     example 1: transport = ['foot', 'bike', 'car', 'plane'];
  // *     example 1: pos(transport);

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 %}
transport = ['foot', 'bike', 'car', 'plane'];
pos(transport);
{% endcodeblock %}

Should return
{% codeblock lang:js returns %}
'foot'
{% endcodeblock %}
