Front-end development focuses on the user interface and user experience, while back-end development deals with server-side logic, databases, and application functionality.

Understanding the distinction between front-end and back-end development is crucial for anyone involved in web development. Front-end development, often referred to as the 'client side,' is concerned with everything that users interact with directly in their web browsers. This includes the layout, design, and interactive elements of a website or web application. Front-end developers use languages like HTML, CSS, and JavaScript, along with frameworks and libraries like React or Vue.js, to create visually appealing and user-friendly interfaces. Their primary goal is to ensure that users have a seamless and engaging experience when using the application. On the other hand, back-end development focuses on the 'server side,' managing the logic, database interactions, and application functionality that occur behind the scenes. Back-end developers use languages like Python, Ruby, or Node.js to handle server requests, process data, and communicate with databases. They are responsible for ensuring that the front end has the necessary data and resources to function correctly. Both front-end and back-end development are integral to the overall web development process, requiring collaboration and integration to create fully functional applications.
