Front-End (UI/HUD)

FiveM uses a feature called NUI(short for 'new UI'), which allows developers to create user interfaces for their scripts using HTML, CSS, and JavaScript. This means you can create things like menus, scoreboards, or huds that show things like the player's money. It's like designing a website, but for a game. The best part is that you can use all the cool features of these web technologies to make your game look and feel exactly how you want it to.
