Using variables in an array

General
1

In my function-Node I have to construct the following msg.payload. I am able to use a variable for the id as well for the value of "Fieldname" but I can't figure out how or if I am able to use a variable to describe the path

msg.payload = [{
    id: iVar,
    fields : { "CAN-THIS-BE-A-VARIABLE-?" : tVar }
}];

Thank you for any help in advance!

This is the best I can do to get what I want working.

Just wanting to check I'm not missing any elephants.

Ok sry to spam the forum I think I got it by trying random stuff xD ... apprently you have to enclose it to brackets [var]

msg.payload = [{
    id: iVar,
    fields : { [fVar] : tVar }
}];

Hope it helps someone
