General query

Hi all

I would like to produce a stamp duty tax calculator for my website.

Please can you confirm which coding language or Codecademy course would help me achieve this.

Kind Regards

Any programming language can help you achieve that.
But if you already have a website and know html and css I think the inevitable choice would be to learn Javascript.
If you know nothing about programming but you need a language that can give you the fastest computation for this or other future projects than C or Rust are your candidates. I don’t know if Codeacademy has a Rust course though.
If you just want to learn a programming language in order to make yourself that specific program, I would advise to look for some specific project or tutorial on how to do that or something quite similar and follow through that.
