​
var funcMap = {
  'a': 1,
  'b': 2,
  'c': 3,
  'd': 4,
  'e': 5
}

​
function getRandomKey() {
  var rIdx = Math.floor(Math.random() * 5);

Tests:

  • using funcMap

     
    var key = getRandomKey();
    var x = funcMap[key];
    console.log(x);
    ​
    ​

  • using switch

     
    var key = getRandomKey();
    var x;
    switch(key) {
        case 'a': x = 1; break;
        case 'b': x = 2; break;
        case 'c': x = 3; break;
        case 'd': x = 4; break;
        case 'e': x = 5; break;
    }
