How to create a new object in Javascript?

In JavaScript, there are several ways to create a new object:

1. Object literal notation:

   You can create an object using curly braces {} and adding key-value pairs separated by colons :.

   For example:

   const car = {
     model: "S",
     avg_speed: 60,
   };

2. Constructor function:

   You can create an object using a constructor function, which is a special function that creates and initializes objects.

   For example:

   function Car(model, avg_speed) {
     this.model = model;
     this.avg_speed = avg_speed;
   }
   
   const car = new Car("S", 60);

3. Object.create() method:

   You can create an object using the Object.create() method, which creates a new object with the specified prototype object and properties.

   For example:

   const car = Object.create(null);
   car.model = "S";
   car.avg_speed = 60;

4. Class syntax:

   You can create an object using the class syntax, which is a new way to define objects in JavaScript introduced in ECMAScript 6.

   For example:

   class Car {
     constructor(model, avg_speed) {
       this.model = model;
       this.avg_speed = avg_speed;
     }
   }
   
   const car = new Car(model, avg_speed);
