JavaScript Maths Abilitity

[tntcoder]

Hey,

I'm planning a project and sadly I have to use JavaScript. I haven't used it for anything sizeable before, but basically I will need to do a fair bit of intensive maths.

Namely, Lagrange polynomial Interpolation and Reed Solomon Code Creation

Is this going to be possible in JavaScript? e.g Is threading an option, so I could move any CPU intensive maths to another thread or wishful thinking?

Thanks,

Jack

Can I ask why you need to implement it in Javascript first? Why can't you pass it via JSP or whatever Java / C++/ C / Fortran?

It's basically for a Firefox extension.

I do have the option of using XPCOM C++ components and invoking them from the JavaScript, but if I can do everything in JavaScript that would reduce the complexity and increase the portability for the project as a whole.

Is it a really bad idea trying to do it in JavaScript?

Thanks, I will need to use Lagrange Interpolation on about 65000 polynomials. Then I will need to use Reed Solomon to create error correction data for about 500kb-1mb of data.

If possible my aim is to do it all without disrupting the Firefox UI responsiveness. Might be tricky with no multi threading
