reverse a string

gistfile1.js

// Sure seems like a lot of code just to reverse a string!
// Define a function reverse() that computes the reversal of a string. For example, reverse("jag testar")
// should return the string "ratset gaj".
var new_str = ""
function reverse(string) {
  for (var i = string.length - 1; i >= 0; i--) {
    new_str += string[i];
  }
  return new_str;
}

console.log(reverse('jag testar'));
var string = 'ratset gaj';
console.log(new_str === string);
