Someone asked about integer support in JavaScript. JS now supports BigInt! >2**57 144115188075855870 >2n**57n 144115188075855872n

  Yes, I was asking about that and I'm very happy to see this exists now.

  And in some JavaScript engines (eg V8) bigint multiplication is asymptotically fast, unlike say the default CPython. It’s a very pleasant surprise if you happen to be a number theorist (say).

    How do you mean? CPython uses karatsuba's for large numbers which should be asymptotically fast https://github.com/python/cpython/blob/d864b0094f9875c5613cbb0b7f7f3ca8f1c6b606/Objects/longobject.c#L3816 https://github.com/python/cpython/blob/d864b0094f9875c5613cb...

  Oh thank god. I've been having to do some hacky things to represent numbers on an astronomical scale for my star system/planet generators.
