JS: Object.getPrototypeOf

By Xah Lee. Date: . Last updated: .

Object.getPrototypeOf ( obj )

Return the parent of object obj.

If obj is not a object, it is converted lto object first. If you don't want the conversion, use Reflect.getPrototypeOf. [see JS: Reflect.getPrototypeOf]

console.log (
 Object.getPrototypeOf ( {} ) === Object.prototype
); // true
