Reflect API

Example: Create a data/accessor property

• Data Property

var car = {};
Reflect.defineProperty(car, "make", {
    value: "Honda",
    writeable: true,
    configurable: true,
    enumerable: true
});
Reflect.defineProperty(car, "model", {
    value: "City",
    writeable: true,
    configurable: true,
    enumerable: true
});
Reflect.defineProperty(car, "year", {
    value: 2008,
    writeable: true,
    configurable: true,
    enumerable: true
});

car.make = "Suzuki"; car.model = "Wagon-R"; car.year = 2013;
console.table(car);

┌─────────┬─────────┐
│ (index) │ Values  │
├─────────┼─────────┤
│  make   │ 'Honda' │
│  model  │ 'City'  │
│  year   │  2008   │
└─────────┴─────────┘
