Script Preparation code:

const array = [];
const indexes = [];
const l = 999999;
const iterations = 9999;


for (let i = 0; i < length; ++i) {
	array.push(Math.random());
}

for (let i = 0; i < iterations; ++i) {
	indexes.push(Math.floor(Math.random() * l));
}

Tests:

Array.at(i)
let total = 0; for(let i = 0; i < iterations; ++i) { const index = indexes[i]; total += array.at(index); } console.log(total);
Array[i]
let total = 0; for(let i = 0; i < iterations; ++i) { const index = indexes[i]; total += array[index]; } console.log(total);
