Hi Stefano,

I am changing the subject line to "SqueakJS for Scratch" because google
sends me somewhere else for "ScratchJS".

I think that you are asking about running Scratch on Bert Freudenberg's
SqueakJS, which is a modern Squeak virtual machine implemented entirely
in JavaScript for HML5, rather than the traditional compiled virtual
machines that run on operating systems such as Linux and Windows.

If I understand your question correctly, you are asking about how to
run Scratch on SqueakJS locally on your PC, and you want to understand
where the Scratch files are stored on your PC.

I do not have good answers to your questions but I am sure that others
on this list can help. I am also CC'ing the squeak-dev mailing list
where some of the real Scratch and SqueakJS experts reside.

Here are some useful links for SqueakJS information:

  https://squeak.js.org/
  http://try.squeak.org/
  https://github.com/bertfreudenberg/SqueakJS

And for Scratch:
