Explain
Unity uses a component-based architecture where GameObjects hold components like scripts, renderers, colliders, and audio.
Developers build interactions using C#, shaders, animations, and prefab-based architecture.
Unity supports exporting to 25+ platforms including Android, iOS, Windows, macOS, WebGL, PlayStation, Xbox, and VR devices.
