A web application, also known as a web app, is nothing but a computer program that uses a web browser to perform a specific function. A web application is a client-server program that comprises a client-side and a server-side. The user enters data through the client-side (front-end), while the server-side (back-end) of the application stores and processes the information. For example, shopping carts, content management systems, and online forms are typical web applications.
