Adding 3D to a website sounds intimidating, but Three.js makes it surprisingly approachable.

I started by rendering a spinning cube — a “Hello World” of 3D. Just a canvas element, a scene, a camera, and some lighting. It took just a few lines of code.

Why I’m hooked:

- It’s GPU-accelerated and smooth.
- There’s a huge ecosystem of examples and libraries.
- It opens the door to games, data visualizations, and interactive UI.

If you’re comfortable with JavaScript and want to try something visual, I highly recommend giving Three.js a spin.
