Benchmark: Switch vs Object Literal vs If-Else

Script Preparation code:

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

Tests:

Switch
switch (str) { case 'a': console.log('A'); break; case 'b': console.log('B'); break; case 'c': console.log('C'); break; }
Object Literal
var objLiteral = { a: function() { console.log('A'); }, b: function() { console.log('B'); }, c: function() { console.log('C'); } } objLiteral[str]();
If-Else
if (str === 'a') { console.log('A'); } else if (str === 'b') { console.log('B'); } else if (str === 'c') { console.log('C'); }
