I've been watching the development of Node.js and frameworks like Express for a while. I finally found some time to play around and am enjoying it.
Does anyone know why Node's current version is only 0.10.0? I know it doesn't really matter but it makes it seem like an extremely new and unstable project when in fact it seems that it's being used quite a bit and even by some big players.
Well, it is new, it's only been around since 2009.
That may seem old to you whippersnappers but I primarily program in a language from the '70s and sometimes on machines that have been around since the '60s.
But seriously, it probably has more to do with the numbering scheme than any actual immaturity. As you can see here, there have actually been quite a few releases.
If you wait a little while, the release plan calls for a 0.12 (code cleanup mostly) to be followed by 1.0 which, based on comments, will be the "final" product (though there will still be more versions since predictions aren't perfect). Many projects start with a (crappy) 1.0 and improve that. The philosophy for node.js seems to have been to approach 1.0 as the fully-polished end product.
