A QBASIC implementation in JavaScript.
Because it uses AJAX to retrieve the .BAS file, you cannot run it using a file:/// url in most browsers. You have to start an http server to run it. (python -m SimpleHTTPServer is a quick one)
You can read the blog post about the library at stevehanov.ca/blog/index.php?id=92.
WARNING WARNING I only implemented enough of the language to run NIBBLES.BAS! It probably won't run your program and my parser makes it difficult to debug what is wrong. I think it would take several years of effort to do the whole language. This is not worth mine or anybody's effort, since you can run the real QBASIC in a javascript dosbox emulator these days... (for example https://js-dos.com/)
If I were doing it again, I would replace the parser with a packrat parser such as peg.js.
