Like, one that you can access with set variable blocks but doesn't appear in the variables palette. maybe a separate block for reporting hidden variables;
(hidden variable [ v]::variables
window.<variable name> = '<variable value>';
To get the value:
window.<variable name>
And to call it?
Are you sure it's
And not
window.<variable name> = '<variable value>'
can you share a project with that code?
it's not that hard to copy.
yes, but I have a break from school right now and it will end soon 
that doesn't work, how do you make a variable?
set variable = make variable
How is this topic a "help with Snap!" topic. This is exactly the kind of question that scares off our target audience. Again, if I see more of these topics I will take out the JS function block. And I will propose to ban those who can't stop obsessing about such "secrets".
