Separate Javascipt code from pure Perl code

[Nikos]

Is there a way to put those 2 javascript snippets that are currently
embedded inside index.pl into 1 or 2 separate files because index.pl
now has gone very huge, but also index.pl to remain functional?

Will the variables for example $data will be able to pass from
index.pl => script1.js => index.pl ?! because both javascript snippets
use variabels of index.pl and have action with them....

Oh yes, then 'do', 'use' etc. could do it.

This is how to call he scripts, if only i had a way to pass the $data
varibale as well including call, can you help with that too perhaps?
