Automatically key insert

[maiconcarlosp]

How may I insert automatically this object information to create new keys.

Value to be automatically insert, value of payload.measurementTypeCode

I tried this below, but return an error: expected ":" and instead saw "."

var data = {
    msg.payload.measurements[0].measurementTypeCode.toString() : msg.payload.measurements[0].measurementValue.toString()
  }

This is called square brackets notation...

var data = {}
data[msg.payload.measurements[0].measurementTypeCode] = msg.payload.measurements[0].measurementValue;
msg.payload = data;
return msg;

That will obviously only do the first element in the payload array.
