riadbendraoua-byte/works.js ? reverse-engineered prompt

Build me a small JavaScript practice project with a few simple example files that each demonstrate one basic thing, like saying hello, asking someone’s age, a tiny greeting bot, simple math operations, and a few string examples.

I want it to be easy to open and run each file on its own, with clear comments so a beginner can understand what’s happening. Keep the code straightforward and readable, and make sure each example actually works without needing anything fancy.

If it makes sense, organize it so the examples feel like a little learning set, not a big app. I’d also like a short README that explains what each file does and how to try them out. If you need to look up current JavaScript syntax or best practices, go ahead and do that.
