if you wan't to use small solutions for global variables in javascript - use window-variables (storyline is technical a single-page application)

https://javascript.info/global-object

example

javascript trigger 1:

function hallo(){
   window.myText = "hallo";
}


javascript trigger 2:

function printHallo(){
   console.log( window.myText );
}

normaly window variables are not used*, the normal javascript would be

var myText;

function hallo(){
    myText = "hallo";
}

function printHallo(){
    console.log( myText );
}

the result is the same, but this it is not possible in a trigger javascript
