Recursive and iterative string reversal in JS... Cuz work is boring.

reverse.js

var reverse = function(str) {
  str = str.split('')
  var end = str.length - 1
  for (var i = 0; i + 1 <= end - i; ++i) {
    var t = str[i]
    str[i] = str[end - i]
    str[end - i] = t
  }

  return str.join('')
}

var reverseR = function(str) {
  return str.length > 1 ? str.slice(-1) + reverseR(str.slice(1, -1)) + str[0] : str
}

var reverseCheat = function (str) {
  return str.split('').reverse().join('')
}
