The dollar sign comes before the opening curly brace:

document.writeln(`Hello ${n}`);


function sayHello(n){
    document.writeln(`Hello ${n}`);
}
sayHello("Andy Anderson");

Dollar sign placement is odd. It should be in the string.

document.writeln(`Hello ${n}`);

The reason you didn't get an error was that the $ is likely defined as a function in your environment, so it was used as a "tag" for the template literal.
