What Is Front-End Developer?

Front-End Developer

Front end developer is a specialist who focuses on the visitor-facing aspects of a website, contrasting with back end developer, who handles the 'behind the scenes' work. A front end developer ensures that users can seamlessly interact with a website, combining design, technology, and programming.
