Object-oriented Programming in
JavaScript

Object-oriented programming (OOP for short) is a style of programming that involves
separating the code into objects that have properties and methods. Sound familiar?
JavaScript obviously supports objects, as we saw in Chapter 5 , so it also supports an object-
oriented style of programming. In this chapter, we'll look at what object-oriented program-
ming is and how to implement it in JavaScript.

In this chapter, we'll cover the following topics:

• an introduction to OOP

• constructor functions

• prototypes

• public and private methods

• inheritance

• creating objects from objects

• adding methods to built-in objects

• mixins

• chaining functions

• this and that

• borrowing methods from prototypes

• our project―create questions in an OOP way
