Read out a global variable


I am trying to read one specific value out of the global variable 'token'. But like you can see, the result is 'undefined'. So I think that the first lane isn't correct, can anyone help?


You are trying to read the global TOKEN but that is not a global variable you have defined. If you said var VALUE = global.get("rfid") || [] you would get something back.
You then use VALUE.TOKEN to access it’s contents.

P.s. why are you using a capital letters for variable names?
