As seen in a recent Node-RED issue where the "bug" was actually in a custom node (now fixed). It is all too easy for node authors to break parts of Node-RED.
One small but useful way to help mitigate this is for Editor javascript to be wrapped in an IIFE:
```javascript
(function () {
'use strict'
// .... "global" code here ....
RED.nodes.registerType(moduleName, { /* .... */ });
}());
```
This immediately prevents leakage of "global" definitions from impacting Node-RED itself and does not seem to have any negative impacts (I've been using this in my own nodes for many years now).
I think it would be a useful tweak to use this pattern in documentation and in the lowercase example node.
