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);
