A-Frame lets you build VR and AR experiences using plain HTML instead of wrestling with WebGL or Three.js directly. You get an entity-component architecture where you can drop primitives like boxes and spheres into a scene, add animations with HTML attributes, and have VR controller support working without touching much JavaScript. It's genuinely good for prototyping immersive experiences fast or adding 3D content to web pages when you don't want to manage a full game engine. The declarative approach means you can sketch out a scene in minutes, though you'll still write custom components in JavaScript when you need real interactivity beyond basic animations and clicks.
