IF vs IF-ELSE vs Switch Case vs Lookup Table - 2 Options (v2)

Revision 2 of this benchmark created on

Setup

function getRandomOption() {
    const options = ["Option 1", "Option 2", "unknown"];
    const randomIndex = Math.floor(Math.random() * options.length);
 
    return options[randomIndex];
}

const randomOption = getRandomOption();

IF-ELSE-IF

} else if(randomOption === "Option 2") {

SWITCH-CASE

		console.log(1);
		break;

Lookup Table
const results = {
	"Option 1": () => {
		console.log(1);
	},
	"Option 2": () => {
		console.log(2);
	},
}

results[randomOption] ? results[randomOption](): console.log('NONE')
ready
Bonus: Switch Pattern Matching
switch(true) {

		break;
	case randomOption ===  "Option 2": 
		console.log(2);
		break;
