Frontend performance refers to the speed, efficiency, and responsiveness of a website's user interface. It encompasses the load times of web pages, the smoothness of animations, and the overall user experience.
Factors influencing front-end performance include asset optimization, code efficiency, and server-side configurations. It largely depends on the web dev stack you are using.
Web performance today is more than just a technical concern and certainly not something you do once and then forget. Because it affects accessibility, design, development, search engine optimization, and user experience (UX), you need to track and measure frontend performance KPIs regularly.
