Hello. I’ve read and gone over the basic info on creating an agent, but where I am getting stuck is the Node Codes and Java Scripts. It’s difficult to understand that part. Are there any books or courses i can take for a beginner? Any suggestions?

Welcome @hecai to our community! I’m Jay and I am a n8n verified creator.
The Code node in n8n runs standard JavaScript, so any beginner JS resource will get you started - MDN Web Docs and freeCodeCamp both cover the fundamentals well and are free. For n8n-specific material, the official courses at Text courses | n8n Docs cover the Code node directly with hands-on examples. For AI Agents specifically, start small - build a Code node that does one transformation (like cleaning or filtering data from a previous node), then connect it as a Tool in the Agent to get familiar with how data flows in and out.
For the basics of JavaScript, you won’t need a full course, just enough knowledge to work with n8n data. JavaScript.info is a reputable free resource; most of what you need are the first few chapters.
Regarding n8n specifically, the official docs have a section on expressions and code worth bookmarking. You can also find solid beginner walkthroughs on YouTube.
Luckily you don’t need to write that much JS from scratch. Most Code nodes use cases just transform or filter data, once you see a few examples it will click pretty quickly.
