Test name	Executions per second
using funcMap	86974.1 Ops/sec
using switch	88378.8 Ops/sec

Script Preparation code:


var funcMap = {
  'a': function() { return 1; },
  'b': function() { return 2; },
  'c': function() { return 3; },
  'd': function() { return 4; },
  'e': function() { return 5; }
}


function getRandomKey() {
  var rIdx = Math.floor(Math.random() * 5);
  return Object.keys(funcMap)[rIdx];
}

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; } console.log(x);
