Benchmark: Object Literal vs Prepared Array

Script Preparation code:

let objLiteral = {
  0x0: ()=> {
    console.log('A');
  },
  0x1: ()=> {
    console.log('B');
  },
  0x2: ()=> {
    console.log('C');
  }
}

var arrayLiteral = [
  ()=> {
    console.log('A');
  },
  ()=> {
    console.log('B');
  },
  ()=> {
    console.log('C');
  }
];

Tests:

Object Literal
objLiteral[Math.floor(Math.random() * 0x3)]();
Array Literal
arrayLiteral[Math.floor(Math.random() * 0x3)]();
