Web Application Development: Description and Features
What is Web Application Development?
Web application development refers to the process of designing, building, testing, and deploying applications that run on web browsers. These applications can be accessed via the internet and do not require installation on a user’s device. Web apps are developed using technologies like HTML, CSS, JavaScript (React, Angular, Vue.js), backend frameworks (Node.js, Django, Flask, Ruby on Rails), and databases (MySQL, MongoDB, PostgreSQL, Firebase).
