Yeah, an all-numpy version runs in less than 1ms on my M1 air

  import numpy as np
  l = 10_000
  t = np.empty(l, dtype=np.float32)
  j = np.arange(l)
  t = 0.02 \* j
  t *= (0.03 * j)
  t -= (0.04 \* j)
  t /= 0.05 \* (j + 1)

So rather than spend 10-20 minutes reading about numpy, the author wrote 3 other implementations...?

The fact that they ran the C code without the optimisation flags and compared it that way makes me think Javascript was what they actually wanted to write this one in anyway.

The author, by the looks of it from the article, is a uni student. Rather than straw-manning this into a language war, we should laude the fact that they managed to write the same thing in a number of different languages to begin with.
