Ok, maybe not "quite a few" -- most of the other ones are implemented in Javascript. The only C++ ones I could find were - https://npmjs.org/package/hashtable ( https://github.com/isaacbwagner/node-hashtable) - https://npmjs.org/package/dht (https://github.com/tilgovi/node-dht) A github search for "hash table" returns 107 C hits and 64 C++ hits, so there are a lot to choose from, you would just need to write node bindings<http://nodejs.org/api/addons.html>. Here are some pages that may be helpful if you're interested in picking & choosing: - a great breakdown of the performance characteristics of the top hash table implementations<http://preshing.com/20110603/hash-table-performance-tests> - a detailed comparison of a Judy Array and a fine-tuned hash table<http://preshing.com/20130107/this-hash-table-is-faster-than-a-judy-array> - a different comparison of hash table libraries<http://attractivechaos.wordpress.com/2008/08/28/comparison-of-hash-table-libraries/> . -- peter On Wednesday, August 21, 2013 10:04:17 PM UTC-7, Peter Rust wrote: > > If all you need is a hash table, there are a lot of hash table C/C++ > libraries that you could integrate with Node (like > Judy<http://judy.sourceforge.net/>) > and there are a few that have already been integrated, like > https://npmjs.org/package/hashtable (that specifically lives outside of > v8's memory constraints) > > > The hash strategy behind the scenes must be interesting > > I found this page that describes (at least some of) what's happening > behind the scenes: > https://developers.google.com/v8/design?hl=sv&csw=1#prop_access. v8 is > creating a new dynamic behind-the-scenes class when you add properties.
