Method 5 : Object.getOwnPropertyDescriptors

Method 4: JavaScript async and await

The Object.getOwnPropertyDescriptors() method in JavaScript is a standard built-in object which returns all property descriptors of a given object.

Syntax:

Object.getOwnPropertyDescriptors( obj )

Example: In this example, we will see the basic use of the Object.getOwnPropertyDescriptors() method in JavaScript.

Javascript

let geeks1 = { 
    prop1: "w3wiki"
} 
let geeks2 = { 
    prop2: "Best Platform", 
    prop3: "And Computer science portal"
} 
const descriptor1 = Object.getOwnPropertyDescriptors(geeks1); 
const descriptor2 = Object.getOwnPropertyDescriptors(geeks2); 
console.log(descriptor1.prop1.enumerable); 
console.log(descriptor2.prop2.enumerable); 
console.log(descriptor1.prop1.value); 
console.log(descriptor2.prop2.value); 
console.log(descriptor2.prop3.value);

Output

true
true
w3wiki
Best Platform
And Computer science portal

JS 2017 – ECMAScript 2017

JavaScript (JS) 2017, or ECMAScript 2017, introduced some new features in JavaScript. It enhanced asynchronous programming with async functions, provided shared memory and atomics for improved concurrency, and introduced Object.values() and Object.entries() for streamlined object manipulation. These additions expanded JavaScript’s capabilities, making it more versatile and powerful for modern development.

JavaScript (JS) 2017 new features are:

String padding
Object entries() Method
Object values() Method
async and await
Object.getOwnPropertyDescriptors

We will explore all the above methods along with their basic implementation with the help of examples.
