NBB: A Small Closure Interpreter for Node.js

NBB is a binary that runs on the JVM and GraalVM. It was developed to replace Babashka, but it can also run in other JavaScript environments like Node.js. The idea for NBB came from using SI, a small closure interpreter used by Clerk's front-end tools. So if you find a library in Node.js that can parse Excel sheets, then you can make a little script that does some conversion and converts it into closure data. And you can make little scripts like that.
