Express Framework Practice Exam

Express Framework Practice Exam

Express Framework is a lightweight web application framework built on top of Node.js. It helps developers create websites, APIs, and web applications quickly and efficiently. Instead of writing complex code from scratch, Express provides ready-to-use tools and features to handle routing, requests, and server responses. This makes building applications faster and more structured.

It’s one of the most popular frameworks in the JavaScript ecosystem because of its simplicity and flexibility. Express is widely used to power everything from small websites to large-scale applications like e-commerce platforms and social media apps. It is the backbone of many modern web services that require speed, scalability, and ease of maintenance.
