A front-end developer in a good development agency has the primary duty to make sure that users of the website can easily interact with the page. They accomplish this by combining programming, design, and technology to code a website’s aesthetic and take care of debugging. The part of websites and online applications that users actually view and interact with is built by front-end developers. Using web languages like HTML, CSS, and JavaScript, a front-end developer develops websites and applications that people can access and utilise.
