What is it?
Express is a web application framework that provides a robust set of features to develop web and mobile applications. It facilitates the rapid development of Node.js based server-side applications. Express streamlines the process of building server-side routes and middleware, making it easier to handle HTTP requests and responses.
What are the key use cases?

API Development

Express is commonly used to build application programming interfaces (APIs) that allow frontend applications to communicate with a server. It simplifies the process of receiving requests and sending responses in JSON or other formats.

Web Applications

Web developers use Express to create interactive, dynamic websites. It handles web application functionalities like managing sessions, processing forms, and implementing authentication.

Middleware Integration

Express allows developers to easily integrate middleware - software components that process request data before it reaches the final handler. This is useful for adding additional layers of functionality to web applications, such as logging, security enhancements, and user session management.

Why would somebody want to learn it?
Understanding Express opens doors to server-side web development using JavaScript, which is a highly sought-after skill in the development community. With its minimalistic approach, learning Express provides a straightforward path to creating efficient web applications and services. It\u2019s a stepping stone towards mastering full-stack development and enhances a developer\u2019s ability to contribute to a wide range of projects.
Who uses it?

Back-end Developers

Back-end developers utilize Express to create the server-side logic of web applications and services. They write code that interacts with databases, manages user connections, and executes server-side application logic.
