I'm using Node-RED more and getting better with Javascript and using the Function Node. I have discovered by trying Jsonata on a very limited basis. NOW with recent improvements to the basics available in Node-RED there is probably a way to use the available resources to limit the "Function" Nodes and do very similar, more efficient programming using Jsonata inside the core nodes where available.

There may be many like me that do not use Jsonata enough to be fluent, but may benefit and leverage the resources already available and embedded.

Can you provide a topic dialog on usage/examples and a Guide on efficient, effective use of Jsonata expressions in the nodes that can use Jsonata expressions.

1. What Jsonata is/is not

2. Things you can do with Jsonata in core nodes. Target functionalities
a . Change Node
b. .. ???

3. simple expressions and how to use variables
a. node
b. flow
c. global

4. Pitfalls, fallacies / things that you cannot/ should not do with Jsonata Things to avoid.

5. ...
