The difference between front-end and back-end development lies in their focus areas within web development. Front-end development pertains to the visual elements of a website or application, encompassing the design, layout, and user interactions. Tools like HTML, CSS, and JavaScript are commonly used in this domain. Conversely, back-end development deals with the server side, focusing on database interactions, server logic, and application functionality. It entails managingdata storage, user authentication, and server integration, often utilizing languages like Python, Ruby, or PHP. Together, both aspects work harmoniously to create fully functional websites and applications.
