function calls: direct vs apply vs call vs bind (v19)

Revision 19 of this benchmark created by Eamon Nerbonne on

Description

Testing various ways to invoke a function, including several ways to manipulate its 'this'.

(2013-12-07 Removed buggy bind2 implementation what was distorting the results)

Preparation HTML

<script>
var f = function() {
  return [];
};

var that = {
  f: f
};

var bound = f.bind(that);

var wrappedCall = function() {
  f.call(that);
};

var slice = Array.prototype.slice;

var name = 'f';
</script>
