Front-end & back-end: differences and development features

This article is devoted to modern web programming tools. When developing web applications, many people come across such concepts as front-end and back-end. These two concepts appeared as a result of the development of the principle of separation of responsibility among programmers. Although these two concepts are different from each other, they cannot work without each other. They complement each other. Front-end development deals with the appearance of the web application that the user is working with, and back-end development is aimed at working with user information received from the front-end. In general, both sides of development are important and necessary, they must work together.
