Benchmark: Object property access or saved pointer

Script Preparation code:

var data = {
    id: 1,
    a: 1,
    b: '',
    c: '',
    d: false,
    e: '',
    f: 1,
    g: {
        h: 1,
        i: 'Dannag'
    },
    k: 1,
    l: 1,
}

Tests:

Property access
let result = 0; for (const property in data) { if (typeof data[property] === 'number' && Number.isInteger(data[property])) { result += data[property]; } }
Pointer
let result = 0; for (const property in data) { const value = data[property]; if (typeof value === 'number' && Number.isInteger(value)) { result += value; } }
