Benchmark: get x versus array[0]

Script Preparation code:

// Setup phase - common for both tests
const size = 10000;
const array = new Array(16).fill(1); // Fill array with ones for consistency

const obj = {
    get x() {
        return array[0];
    },

    set x(value) {
        array[0] = value;
    }
};

Tests:

array[0]
let sum = 0; for (let i = 0; i < size; i++) { array[0] = Math.random () * 1000; sum += array[0]; }
set / get
let sum = 0; for (let i = 0; i < size; i++) { obj.x = Math.random () * 1000; sum += obj.x; }
