Web application

A web application or web app is any computer program that runs in a web browser.

Description

A web application is created using browser-supported programming languages, such as the combination of JavaScript, HTML and CSS.

Web applications typically modify the Document Object Model to display output.

Benefits and popularity

Web applications are popular due to the ubiquity of web browsers, and the convenience of using a web browser as a client, sometimes called a thin client.

The ability to update and maintain web applications without distributing and installing software on potentially thousands of client computers is a key reason for their popularity, as is the inherent support for cross-platform compatibility.
