Front-end development and back-end development refer to the two main parts of developing a website or web application.
Front-end development, also known as client-side development, is concerned with the design, layout, and interactivity of a website. Front-end developers use technologies such as HTML, CSS, and JavaScript to create the user interface and ensure that the site is visually appealing and user-friendly. The goal of front-end development is to create a seamless and enjoyable experience for the end user.
Back-end development, also known as server-side development, is focused on the functionality and performance of a website. Back-end developers use programming languages such as Python, Ruby, or PHP to build the underlying systems that power the website, such as databases and server-side scripts. The goal of back-end development is to ensure that the site runs smoothly, quickly, and securely.
In short, front-end development is concerned with what the user sees and interacts with, while back-end development is concerned with what goes on behind the scenes to make the site work. Both front-end and back-end development are essential for creating a complete and functional website or web application.
