App Building & Devbeginner
Frontend
Definition
The part of an application users see and interact with, the visual interface built with HTML, CSS, and JavaScript that runs in the browser.
Why it matters
The frontend is your product's first impression. Good frontend design converts visitors; bad frontend loses them regardless of how good the backend is.
Example
A founder's course platform frontend shows the video player, lesson list, progress bar, and purchase button. The backend handles whether the user has paid.
