PLEASE NOTE  The documentation says      filter is a JavaScript extension to the ECMA-262 standard  as such   it may not be present in other implementations of the standard  You   can work around this by inserting the following code at the beginning   of your scripts  allowing use of filter in ECMA-262 implementations   which do not natively support it  This algorithm is exactly the one   specified in ECMA-262  5th edition  assuming that fn call evaluates to   the original value of Function prototype call  and that   Array prototype push has its original value    So  to avoid some heartache  you may have to add this code to your script At the beginning   if   Array prototype filter      Array prototype filter   function  fn  context        var i          value          result               length          if   this    typeof fn      function      fn instanceof RegExp               throw new TypeError                      length   this length          for  i   0  i  lt  length  i                if  this hasOwnProperty i                 value   this i               if  fn call context  value  i  this                   result push value                                           return result
