What is the difference between a front-end developer, a back-end developer, and a full-stack developer?

Difference between front-end, back-end, and full-stack developer: Front-end developers focus on the user interface and user experience of a web application, using technologies such as HTML, CSS, and JavaScript. And can be mastered from full stack web developer course

Back-end developers focus on the server-side of the application, using languages such as Python, Ruby, or Java and frameworks such as Node.js. Full-stack developers are proficient in both front-end and back-end development and can develop an entire web application from start to finish.
