Which keyword is used to define a class in JavaScript?OptionsclassobjectprototypeClass

The correct keyword used to define a class in JavaScript is class.

In JavaScript, the class keyword is introduced in ECMAScript 2015 (ES6) and provides a more elegant way to create objects and handle inheritance. By using the class keyword, you can create a blueprint for objects that can include methods and properties, just like in other object-oriented programming languages.

This allows developers to write more structured and maintainable code. For instance, a basic class definition would look like this:

class MyClass {
    constructor() {
        // initialization code
    }

    myMethod() {
        // method code
    }
}

The class keyword thus denotes the creation of a class in JavaScript.
