What are the various ways to create objects in JavaScript?

Answer

Objects in JavaScript can be created in several ways:

1. Object Literals:

const obj = { key: 'value' };

2. Object.create():

const obj = Object.create(proto);

3. Constructor Functions:

function Obj() {
  this.key = 'value';
}
const obj = new Obj();

4. ES6 Classes:

class Obj {
  constructor() {
    this.key = 'value';
  }
}
const obj = new Obj();

5. Using new Object():

const obj = new Object();
obj.key = 'value';

6. Factory Functions:

function createObj() {
  return { key: 'value' };
}
const obj = createObj();
