Simple objects equality checker function

areObjectsEqual

// Check if objects are equal (have the same keys with the same values), all values must be primitives (no functions, objects or arrays)

function areObjectsEqual(obj1, obj2) {
    let obj1KeysCount = 0;
    for (const key in obj1) {
        if (obj1[key] !== obj2[key]) return false;
        obj1KeysCount++;
    }
    return Object.keys(obj2).length === obj1KeysCount;
