If I have
msg.payload = {
Element1 :"One",
Element2 : "Two",
Element3 : "Three"
}
return msg;
The output is: {"Element1":"One","Element2":"Two","Element3":"Three"}
But now, If I want to add a new element, how do I do it?
For the output like this: {"Element1":"One","Element2":"Two","Element3":"Three","Element4":"Four"}
Thank you.
try a google search 'json opject adding element to' and see what you find.
Understanding javascript objects is very important for using Node-RED.
I found the following tutorial very helpful
