Online collaboration has become increasingly important in today's digital world, enabling individuals and organizations to connect and work together. One of the key tools used for online collaboration is discussion forums, which provide a platform for users to share ideas, ask questions, and engage in meaningful discussions. The MERN (MongoDB, Express, React, Node.js) project stack is a popular technology stack used for building web applications, and we have made a discussion forum with it that enables users to collaborate and communicate with each other. This paper reviews existing research on the impact of online discussion forums on student engagement and learning outcomes and analyzes the key factors that contribute to their success.
