      You do not understand floating point numbers. 2^53 is not the largest integer that can be represented accurately in 64-bit floats. *All* the integers *from zero to 2^53* can be represented, but *many more larger than that* can too. Just not all of them.

      @asbradbury We will get int64/uint64 in ES7 (which means in top browsers soon, under a flag at first in some) or I will eat my twitter-hat.

      I worked on Int64/Uint64 until others were inspired to see-and-raise by doing BigInt. Win-win, no hat eating.

      Catching up with Python, eh ;-) Seriously though, lack of Uint64 (and ints in general) was a major pain point for a lot of binary processing in JS. The only problem now is that JS got a real int type so late that all the APIs take Number... is there a plan for that?

      https://asmjs.org/  -- JS has int32 and uint32, modern engines optimize accordingly esp. when sourced/sunk via typed arrays. I suggest reading (including the issues) https://github.com/tc39/proposal-bigint … also.

      It's true we could have added many numeric types ages ago, but browser wars I shut down JS standardization after 1999 ES3. When we got it restarted via Firefox it took too long, with divided member effort due to Silverlight, Dart, PNaCl, to find the champions and get tc39 moving.

      I'm not moaning about this, it is pointless to cry over spilled milk, but it seemed you were belaboring the lateness. Anyway, the history is what it was and the best time to have done BigInt was 1995, when (with only me working on JS) I had no time for it. Still sleep-deprived.

      History is what it is indeed. This whole discussion stemmed from an "other languages do/have done this better" talk, which, well, is the case, but fixing things now is better than never. I hope JS finds ways to evolve towards getting rid of these nits. It's definitely not easy!

      My main beef isn't with the language (I can understand why it is what it is, and it's improving) but with those who defend its warts just because they like it. Those people are rarely the ones actually working on the language :-)

          In my experience the worst belly-aching comes from those who haven't done JS in years -- or ever. But YMMV. “There are only two kinds of languages: the ones people complain about and the ones nobody uses.” ― Bjarne Stroustrup, The C++ Programming Language

          I've been really trying to empathize with those that aren't able to see JavaScript for what it is and not for how it isn't like _insert language here_. I wish there was more compassionate learning material to share that taught the whys in a less dogmatic way. Any suggestions?
