Possible Noob-question - yes i have seached in the docu and have found not an answer.
I create a msg with:
var num = msg.payload;
msg.payload = [{ "Test": parseFloat(num) }];
return msg;
Now i want to replace the "test" with a variable.
var num = msg.payload;
var testindex = "Test"
msg.payload = [{ testindex: parseFloat(num) }];
return msg;
But this does not work.
It results in an array with "testindex: 1673371589863" - but not with the variable like "Test: 1673371589863" as expected.
Is there a reason why it needs to output an array with a single object ?
a dirty way:
const num = msg.payload;
const property = "test"
msg.payload = [{ [`${property}`]: parseFloat(num) }];
return msg;
Ahhh. Great! That works well.
Thanks for the quick reply!
To the question: It is for the elimination of multiple function nodes to only one and to avoid typos

Just for info. The string template is not needed
msg.payload = [{ [property]: parseFloat(num) }];
Should be fine.
Yeah thats what i thought, it didnt work here (initially), must have made a typo.
Looks good, but does not work.
The result is "undefined: 1673376899329"
