Dynamic referencing within arrays

Hi,
So I’m having trouble referencing within an array that is a result of a database query.
I’ll simplify my problem to a dummy scenario so I have more chance of getting answers.

In the console log my db query result array comes up in this format (all values are strings):

thing1: “X”
thing2: “Y”
thing3: “Z”

I’m trying to get a text element #textOutput to display “X”, “Y”, or “Z” depending on whether thing1, thing2 or thing3 is inputted. This is what I have at the end of my code, but it doesn’t work:

let P = "thing1";
$w("#textOutput").text = item.P.toString();

Yet when I do:

$w("#textOutput").text = item.thing1.toString();

…the text element displays “X” as expected.

But I don’t want P to be hardcoded. I want to be able to reference it as:

item.P

if that makes sense.
What is the correct syntax/method for doing this?

Thank you!

Ok I solved it.
Apparently dot notation doesn’t work: it has to be [] notation for some reason.

i.e.:

$w("#textOutput").text = item[P].toString();
