Benchmark: multie params vs object

Script Preparation code:

function sum(a,b){return a + b}
function sumObj(o){return o.a + o.b}

Tests:

sum multi params
for (let i = 0; i < 100000; i++){ sum(Math.random(), Math.random()) }
sum single param
for (let j = 0; j < 100000; j++){ sumObj({ a: Math.random(), b: Math.random() }) }
sum random param o
for (let k = 0; k < 100000; k++){ if (k % 2 === 0) { sumObj({ a: Math.random(), b: Math.random() }) } else { sumObj({ b: Math.random(), a: Math.random() }) } }
