Some of the most fun I've had coding was building things nobody asked for. A pixel art editor. A random name generator. A "is this number prime?" website. None of these will make money or impress a hiring manager. But they made me a better developer.
Why "Useless" Projects Are Actually Useful
- Zero pressure — no deadlines, no stakeholders, no specs. Pure creative freedom.
- Deep learning — you explore APIs and patterns you'd never touch at work.
- Finishing things — small scope means you actually ship it. That builds confidence.
- Portfolio filler — even silly projects show that you code for fun.
My Pixel Art Editor
I built a pixel art canvas right in the browser. It's a grid of cells that you paint with a selected color. You can resize the grid, pick colors, use an eraser, and clear the whole canvas.
Is it going to replace Aseprite? No. Did I learn a ton about mouse events, canvas state management, and CSS grid? Absolutely.

Takeaway
Build things that make you smile. The best developers I know all have weird little side projects that serve no purpose other than being fun to make.
