Rob Pike tweeted about it (the Android version) recently [1]. I ported [2] the app to the web within a few hours. The port involves ~70 lines of Go, 22 lines of HTML, and 24 lines of CSS [3].

Python seems faster than this gopherjs solution. I thought they'd be about equal or the JS being faster since JS is supposed to be really fast at math. I ran 2123456 in both and Python was quite fast, Ivy on gohperjs quite slow

  Unfortunately, if you write 2[star][star]123456 in a HN comment, the HN software will decide that this means a 2, then an emphasized empty string, then 123456, and the results will be indistinguishable to readers from the much smaller number 2123456.

  Do you have a link to the Python version? What was used to generate it? Also, what browser did you use, I'm curious.

    I believe he means plain python, which automatically promotes big integers to the bigint type

      Oh, ok. I know GopherJS math package uses some native JavaScript funcs that are fast, but I think math/big does not have a native implementation.
