Js Range

range.js

/*
Naive implementation of a range in Javascript. I needed that for a project, and coming from Ruby, I was disappointed to find there wasn't that. 
So I implemented one.
b => beginning value of the range
e = ending value of the range
i => include or not the last value (.. or ... in Ruby)
*/

var array = new Array;

function range(array, b, e, i) {
  if (typeof i == 'undefined') {
    i = true;	// if include is not defined, include by default
  }
  if (e < b){
    if (i == true){
      return array;
    }
    else {
      return array.pop();
    }  
  }
  else {
    array.unshift(e);
   	range(array, b, e - 1, i);
  }
