Although node-RED is a low code tool there are times when you will need to understand some programming concepts and write basic code.
Node-RED works by passing a message object between nodes.
Nodes use this message object and usually return a modified or new message object depending on their function.
The function node node is used to run user created JavaScript code against the msg object.
