The Object defineProperties() method
Find out all about the JavaScript defineProperties() method of the Object object
Creates or configures multiple object properties at once. Returns the object.
Takes 2 arguments. The first is an object upon which we’re going to create or configure the properties. The second is an object of properties.
Example:
const dog = {} Object.defineProperties(dog, { breed: { value: 'Siberian Husky' } }) console.log(dog.breed) //'Siberian Husky' I didn’t just say breed: 'Siberian Husky' but I had to pass a property descriptor object, defined at the beginning of this page.
It can be used in conjunction with Object.getOwnPropertyDescriptors() to copy properties over from another object:
const wolf = { /*... */ } const dog = {} Object.defineProperties(dog, Object.getOwnPropertyDescriptors(wolf)) download all my books for free
