Complex functions with javascript


I’m creating a dynamic website and I wanted to read and write from my website the files located on my server depending of the answers of the users (there are also some calculations … )
I didn’t found these functions in javascript …
Is it possible to use a python script called from js or something like that ?

Thanks a million,

Are either of these worth anything to you? They purport to convert Python to JS; I’d imagine that, if they work, you’d be able to run your Python source through them, then import the results into Hype’s resource library.

…or this…
