err, how is JS inadequate for that stuff? Python does not have fp16 support natively, neither does JS. It also doesn't have fp32, int64, int8, int32, uint32 etc. JavaScript does? JavaScript is 43 times faster for this random workload: (env) bwasti@bwasti-mbp ~ % time python bleh.py python bleh.py 9.27s user 0.06s system 99% cpu 9.352 total (env) bwasti@bwasti-mbp ~ % time bun bleh.ts bun bleh.ts 0.16s user 0.02s system 83% cpu 0.216 total (env) bwasti@bwasti-mbp ~ % cat bleh.py import random v = [0 for i in range(1000000)] for i in range(int(1e8)): v[i % len(v)] += 1 (env) bwasti@bwasti-mbp ~ % cat bleh.ts const v = new Float32Array(1000000) for (let i = 0; i < 1e8; ++i) { v[i % v.length] += 1 } Try as many as you want and you'll see that it just blows python out of the water
