We explored Arquero a year or so ago. It’s pretty cool, can run against data in Apache Arrow format and even transform it to run against WebGPU I think. This makes things run super fast.

It didn’t work for our use case so we didn’t end up using it for long.

I also didn’t like that it parsed and transformed your JavaScript behind the scenes for various reasons. [1]

Honestly, this just leads to a lot of confusion and additional complexity for folks to reason about. I’d have preferred just a non-JavaScript DSL for the stuff they optimize and for things to work exactly the way you expect when you do use JavaScript.

If your data's smaller e.g. you do most of the filtering on the backend but want to transform it to display multiple ways on the frontend, I really enjoy using Tidy.js https://pbeshai.github.io/tidy/. Great API and makes massaging data pleasant.
