Node-red runs on nodejs, which uses Javascript. So you would use Javascript in the function node. You can reference this site for functions/methods/etc

> **[JavaScript reference - JavaScript | MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference)**

> This part of the JavaScript section on MDN serves as a repository of facts about the JavaScript language. Read more about this reference.

Also see [Writing Functions : Node-RED](https://nodered.org/docs/user-guide/writing-functions)

I recommend watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
