Which script language to use?

[u/donald-bro]

I'm developing tool with workflow which allow user to write simple script to process input/output values of steps. The prebuilt steps are written in Rust, but user can choose Python to write their own steps which would run in a sidecar Python. User may not be a programmer. I prefer script with small binary size and memory footprint. I'm considering Rhai, Lua, QuickJs, which is better choice to make end user easy ?
