sometimes switch is too much

switch-hash.js

var val = {
 "option 1": "value 1",
 "option 2": "value 2",
 "option 3": "value 3"
}[option] || "default value";

// is faster and smaller than:

var val;
switch (option) {
  case "option 1":
    val = "option 1";
  break;
  case "option 2":
    val = "option 2";
  break;
  case "option 3":
    val = "option 3";
  break;
  default:
    val = "default value";
}
