impossible to set a variable to (blank) using JavaScript from an external source?

 @Owen your method works, but as a JavaScript novice the syntax:

var string = "";

window.GetPlayer().SetVar(string);

made more sense to me. Just throwing this out there in case it's useful to other novices like myself.

    There are absolutely multiple ways to do this and the method you proposed does create a variable as a string. Specifically, it creates a string literal.

    Normally, JavaScript strings are primitive values, created from literals:
    let x = "John";

    But strings can also be defined as objects with the keyword new:
    let y = new String("John");

    Interestingly enough, these 2 things are not equal.

    If you tested to see if the values of x and y above were the same (x==y) it would return "true". 
    However, if you tested to see if the value and the type were the same (x===y) it would return false. 

    For this specific question, either will do, but in the spirit of moving you from Novice forward, just know that there is a difference and how you declare a variable can matter.
