What is the difference between front-end and back-end development?

The distinction between front-end and back-end development is fundamental in web development. Front-end development specifically pertains to the client side of a web application, meaning it deals directly with what users interact with visually in their browsers. This includes aspects like layout, design, and user interface elements that contribute to the overall user experience. Technologies such as HTML, CSS, and JavaScript are primarily used in front-end development to create responsive and visually appealing content.

By focusing on user interface and experience, front-end developers ensure that applications are not only functional but also aesthetically pleasing and intuitive for users. This aspect is crucial as it directly affects how users perceive and engage with an application. A well-designed front end enhances usability and can significantly impact user satisfaction and retention.

The other options mistakenly attribute features of front-end and back-end development to each other or suggest that there are no differences at all, which would undermine the distinct roles these two areas play in the creation of web applications.
