Front-end development
Front-end development is the art and science of building the user interface (UI) and user experience (UX) of a website or web application. It's what users see and interact with directly in their browser. A skilled front-end developer translates designs and mockups into functional, interactive web pages using a combination of HTML, CSS, and JavaScript. They ensure the website is responsive, accessible, and performs well across different devices and browsers.
What to look for in a front-end developer
When hiring a front-end developer, look for a strong portfolio showcasing their previous work. Pay attention to the quality of their code, the responsiveness of their designs, and their attention to detail. A good front-end developer should have a deep understanding of:
- HTML: The foundation of any web page.
- CSS: Styling and layout of web elements.
- JavaScript: Adding interactivity and dynamic behaviour.
Experience with popular front-end frameworks and libraries like React, Angular, or Vue.js is often a plus, depending on your project's needs.
