this is absolutely insane!!! I understand capturing the REST api network part, is it then examining the request body, headers being sent back and forth to figure out the API?
From what I understand it’s also somewhat how JIT works in various JavaScript engines: observe the sorts of objects (which naively have the performance characteristics of hash tables) you see, and start defining static offsets for fields you observed. The JIT’d (fast) objects may morph over time as new fields are observed, but I’d imagine it’s a similar idea to creating documentation… “this object tends to have these fields, so just pretend those are the only fields it can have, until another request proves otherwise”, with similar guess/checking for their types/etc.
