Web application development refers to the process of creating a computer program or software that is specifically designed for accessing the internet. The main aim behind it is to develop web-based applications that can be accessed using a web browser – instead of traditional programs – and can allow users to access the application from anywhere in the world at any time. A web developer, who specializes in this technology, is responsible for the creation of complex web applications that run seamlessly across multiple platforms. It also involves taking into account the functionality and security needs of a business to ensure smoother operations.
