A JavaScript equivalent of PHP's vsprintf

{% codeblock strings/vsprintf.js lang:js https://raw.github.com/kvz/phpjs/master/functions/strings/vsprintf.js raw on github %}
function vsprintf (format, args) {
  // From: http://phpjs.org/functions
  // +   original by: ejsanders
  // -    depends on: sprintf
  // *     example 1: vsprintf('%04d-%02d-%02d', [1988, 8, 1]);
  // *     returns 1: '1988-08-01'
  return this.sprintf.apply(this, [format].concat(args));
}

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 %}
vsprintf('%04d-%02d-%02d', [1988, 8, 1]);
{% endcodeblock %}

Should return
{% codeblock lang:js returns %}
'1988-08-01'
{% endcodeblock %}
