Script Preparation code:

var data = Array.from({length: 9999}, () => Array.from({length: 6}, () => Math.random()))

function sum(a1, a2, a3, a4, a5, a6) {
    return a1 + a2 + a3 + a4 + a5 + a6;
}

Tests:

spread
let a = 0 for (let i = 0; i < 9999; ++i) { a += sum(...data[i]); } console.log(a)
individual
let a = 0 for (let i = 0; i < 9999; ++i) { let datai = data[i] a += sum(datai[0], datai[1], datai[2], datai[3], datai[4], datai[5]); } console.log(a)
Apply
let a = 0 for (let i = 0; i < 9999; ++i) { a += sum.apply(null, data[i]); } console.log(a)
