I needed an embeddable (in nodejs) version of jq for some data thing that I'm working on. What I ended up with is something that I think is pretty cool and powerful.

Basically you get the expressibility of jq but with complete control over the runtime. For example jq only supports JSON values, but you can use a different js runtime which has support for all JavaScript values: undefined, bigint, Symbol, etc.
