What is Web Dev? An Introduction
Web dev encompasses a wide range of activities, all centered around building and maintaining websites and web applications. It’s typically divided into two main areas: front-end development and back-end development. Front-end development focuses on the user interface (UI) and user experience (UX), meaning everything a user sees and interacts with directly. Back-end development, on the other hand, deals with the server-side logic, databases, and infrastructure that power the website or application. Some developers specialize in one area, while others become “full-stack” developers, capable of handling both front-end and back-end tasks. Understanding the difference between these areas is a crucial first step in your web dev journey.
Front-End Web Dev: The User Experience
Front-end web dev is all about creating the visual aspects of a website or application.
