I'm experimenting with some JIT options in SCI on CLJS:

$ NBB_JIT=1 node lib/nbb_main.js -e '(time (print (loop [i 0 j 10000000] (if (zero? j) i (recur (inc i) (dec j))))))'
10000000
"Elapsed time: 8.335917 msecs"
this is as fast as CLJS on V8 with preservation of good error messages

What's the trick? It should not be possible, right? Is cljs missing some optimizations? Just curiosity here if you feel like explaining

this is about as fast as it can get. numeric ops are just compiled and evaluated straight to JS, loops too

cc @mkvlr this also solves the performance problem we once had with emmy in clerk
