Test name	Executions per second
Switch	59416.1 Ops/sec
Object property	58909.7 Ops/sec
Object with arrow funcion	55503.1 Ops/sec
Object with funcion (from the link in description)	57313.0 Ops/sec

Script Preparation code:

var str = 'abc';
str = str.charAt(Math.floor(Math.random() * 3));

Tests:

Switch
const useSwitch = (str) => { switch (str) { case 'a': return 'A'; break case 'b': return 'B'; break case 'c': return 'C'; break } } console.log(useSwitch(str));
Object property
const useObject = (str) => { let letters = { a: 'A', b: 'B', c: 'C' } return letters[str] } console.log(useObject(str));
Object with arrow funcion
var arrow = { a: () => 'A', b: () => 'B', c: () => 'C' } console.log(arrow[str]());
Object with funcion (from the link in description)
var objLiteral = { a: function() { console.log('A'); }, b: function() { console.log('B'); }, c: function() { console.log('C'); } } objLiteral[str]();
