I made this simple interactive star map because I find that the existing programs, some of them very mighty, are a bit complicated to use. My star map contains the 300 brightest stars, the planets visible to the eye, the sun and the moon. The position data is automatically determined, the orientation is not. The star map is a progressive web app (PWA), so it works offline on a smartphone. I wrote this in my own programming language, which runs in the web browser using WASM.
