JavaScript-V8 (0.07) *****

An excellent module.

I used JavaScript::SpiderMonkey before but ran into some limitations and decided to give JavaScript::V8 a try. It took me a while to get it to work on OS X, but it was well worth the effort. It was a big surprise for me how well this module integrates those two languages, almost as if they are one. The JS return-types are converted into proper Perl types and the other way around as well. You can even call JS methods easily from Perl, and the other way around. This made my code much simpler and I could remove large chunks of code that was handling the interaction between the two languages. Thanks a lot!

JavaScript-V8 (0.06) *****

Thank you for this module!

I initially found it hard to install the required libv8 (no rpms for centos, brew on osx didn't work), and the 0.06 release would not compile on perl 5.8.8.

Got the latest code from github and all was fine and dandy - there seems to be quite a bit of work going on at the moment fixing compilation problems.

The docs are slightly misleading - binding a scalar hashref or string/number doesn't work, however binding anonymous subs works fine, as does returning structured data from the js context.

The headline, however is that it was 10x faster than Javascript::SpiderMonkey at the task in hand (loading jsv.js, registering ~80 json schemas from individual files and then running json schema validation), taking ~2s rather than ~20. Once the context was up and running, subsequent calls into it were lightning fast ( as little as 0.006s to run a validation vs a non-trivial schema )
