A JavaScript equivalent of PHP's is_buffer

{% codeblock var/is_buffer.js lang:js https://raw.github.com/kvz/phpjs/master/functions/var/is_buffer.js raw on github %}
function is_buffer (vr) {
  // +   original by: Brett Zamir (http://brett-zamir.me)
  // *     example 1: is_buffer('This could be binary or a regular string as far as JavaScript knows...');
  // *     returns 1: true
  return typeof vr === 'string';
}
{% endcodeblock %}

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:

This code
{% codeblock lang:js example %}
