Detect in script if io.js or node is running #1447
Description
Activity
Since you mentioned it, if process.versions.node does not start with "0.", it's io.js. Might change in the future, but node is pretty slow moving.
I believe you check navigator.userAgent contains "IE".
In all seriousness though I'd be curious what scenario's you have that need to know. Perhaps there's a better way of branching.
Additionally, if io.js and nodejs merges - introducing process.versions.iojs would just complicate things. Since node hasn't bumped to 1.0 just yet, what @monsanto suggested is probably your best bet.
Yeah, the real fix will hopefully be with #493, but it seems a bit stale.
Another alternative is to check process.execPath like I do here:
Check if process.versions.node's major (first number) is 1 (or use node-semver). There have been numerous discussions about this which can be linked to (including the aforementioned #493)
Work-arounds like these are what caused Microsoft to have to skip an entire version for Windows.

Check if process.versions.node's major (first number) is 1
Besides, this advice is broken now with 2.0.0 ;)

I would absolutely adore the ability to check whether Node or io.js is running the script. Perhaps via changing

As it is, the best way seems to be to have the script fork a child_process of the executable that started it, with the -h flag, then to parse for iojs.org
