what does a question mark means in FS coding?

    It's a ternary operator: https://en.wikipedia.org/wiki/?:

    Basically, if you type:
    var x = predicate ? 1 : 2;

    Then if predicate is true, x is set to 1, if it is false, x is set to 2, and if predicate is not a boolean, an error is thrown.
