Front-end web development, also known as client-side development is the practice of producing HTML, CSS and JavaScript for a website or Web Application so that a user can see and interact with them directly. The challenge associated with front end development is that the tools and techniques used to create the front end of a website change constantly and so the developer needs to constantly be aware of how the field is developing.
Back-end Development refers to the server-side development. It focuses on databases, scripting, website architecture. It contains behind-the-scene activities that occur when performing any action on a website. It can be an account login or making a purchase from an online store. Code written by back-end developers helps browsers to communicate with database information. Back-end developers ensure the website performs correctly, focusing on databases, back-end logic, application programming interface (APIs), architecture, and servers.
Full-stack developers are experts in both the frontend and backend; so, the full-stack of technology that makes up a website. They are proficient in both frontend and backend languages and frameworks, as well as in server, network and hosting environments. To get to this breadth and depth of knowledge, most full-stack developers will have spent many years working in a variety of different roles. They also tend to be well-versed in both business logic and user experience, meaning they are not only well-equipped to get hands on, but can also guide and consult on strategy too.
