How to Create a New Instance of a JavaScript Object?

There are several ways to create a new instance of a JavaScript object:

1. Using object literals:

let obj = {};

2. Using the Object constructor:

let obj = new Object();

3. Using Object.create() method:

let obj = Object.create(Object.prototype);

4. Using a custom constructor function:

function MyObject(param1, param2) {
  this.param1 = param1;
  this.param2 = param2;
}

let obj = new MyObject("value1", "value2");

Note: The last method is useful when you want to create multiple instances of the same object type and set their initial state using parameters.
