In the above example, we define an Person Object with certain property and method and then we inherit the Person Object in the Student Object and use all the property and method of person Object as well define certain property and methods for Student. Lets use ES6 classes then we will look into traditional way of defining Object and simulate them as classes. JavaScript classes provide a much simpler and clearer syntax to create objects and deal with inheritance. The class syntax is not introducing a new object-oriented inheritance model to JavaScript. JavaScript classes, introduced in ECMAScript 2015, are primarily syntactical sugar over JavaScript’s existing prototype-based inheritance. Note: Even the classes provided by ECMA2015 are objects. To be more precise, JavaScript is a prototype based object oriented language, which means it doesn’t have classes rather it define behaviors using constructor function and then reuse it using the prototype. A class can have many Object, because class is a template while Object are instances of the class or the concrete implementation.īefore we move further into implementation, we should know unlike other Object Oriented Language there is no classes in JavaScript we have only Object. Classes– Classes are blueprint of an Object.
