Hi all...
Node-Red is supposed to be all about doing the 'programing' visually, but I'm stuck on some function coding.
I'm used to processing data with Excel, so this is the the mind-set/tool-set I'm coming from. I also have very limited coding knowledge. I guess the learning curve is a bit to steep for me:
I am trying to develop linear flows that read and write from the global context dynamically.
The objective is to complement a message with the related values (i.e.: msg.domain, msg.area, msg.effect), based on a given variable in the message (i.e.: msg.reference).
Once a flow runs, it should be able to query the global context automatically and update the message. Then the message could be forwarded and directed by switches based on the newly updated values.
In Excel I would use a =vlookup function and extract the data from one table to another, but given that I started using Node-Red one week ago, I have no clue what to do.
From my 'googling', I was lead to believe that this would work, but I got nothing, not even an error message 
var data = global.get("sample");
var dataResults = data.find(key => msg.reference === key.reference)
if(lookupResults) {
msg.domain = lookupResults.domain;
msg.area = lookupResults.area;
msg.effect = lookupResults.effect;
}
return msg;
Any help is much appreciated,
Cheers!
Sample flow:
