property descriptors

In JavaScript, every object has a set of properties, and each property has its own descriptor. These descriptors define the behavior and characteristics of the property. Understanding property descriptors is essential for working with objects in JavaScript. There are several Object static methods that interact with property descriptors. These methods include: Object.create() Object.defineProperties() Object.defineProperty() Object.getOwnPropertyDescriptor() Object.getOwnPropertyDescriptors() Let’s take a closer look at property descriptors using an example: { value: 'Something' } This is the simplest form of a property descriptor....

The getOwnPropertyDescriptors() method of the Object object in JavaScript allows us to retrieve all own (non-inherited) property descriptors of an object. By using this method, we can obtain a new object that provides a comprehensive list of descriptors. Here’s an example to illustrate its usage: const dog = {} Object.defineProperties(dog, { breed: { value: 'Siberian Husky' } }) Object.getOwnPropertyDescriptors(dog) /* { breed: { value: 'Siberian Husky', writable: false, enumerable: false, configurable: false } } */ One key use case for this method arises from the limitations of Object....
