Working with received data in the expression editor

Question

Hi friends, what are some methods to work with the received data in Expression editor?
For example I get from cms request a list of blog posts :
https://api.baserow.io/api/database/rows/table/123456/
and I need to select three random ones, for block read our blog articles. How to do it? in the same baserow api there is no random parameter, so I need to make random and slice already in webstudio. How to solve this? Maybe there is some tutorial? I don't quite understand how Expression editor works. How freely can js be used there?

Epxression Editor allows only a subset of JS which can be found here https://docs.webstudio.is/university/foundations/expression-editor#expressions

This type of thing you would need to use a backend for, in your case you are using baserow as a backend, if it doesn't allow this you would need a backend in between. I would use a cloudflare worker and build a thin layer between baserow and webstudio if you really need this

Thanks for the replies friends, I get the idea, I'll try to implement it on n8n, it's more familiar to me 🙏
