Nodejs Array Range range(first, second)

Method Source Code

Array.prototype.range = function(first, second) {
  var range = []//from w ww .  j a  v a 2  s  .c  o  m

  console.log(typeof second)

  // only one argument means an array from
  // 0
  if (typeof second === 'undefined') {
    for (var i = 0; i < first; i++) {
      range.push(i)
    }

  }

  // two arguments means an array from
  // 'first' to 'second'
  for (var i = first; i < second; i++) {
    range.push(i)
