OOP is a programming paradigm that revolves around creating "objects." An object encapsulates data (properties or attributes) and the code that operates on that data (methods or functions). Objects interact with each other through messages, promoting modularity and reusability.
Pizza Store Example:
Object: Pizza
Properties: size (small, medium, large), crust (thin, thick), toppings (list of strings)
When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
