needs more tests and moreover, random ones (too bad, it's approvable already, otherwise... :/ )

Rubies done

Yes, updated! thanks

There are errors in your ruby example testcase:

],                                                                            <- ',' missing
  delete: [ { id: "m5", source: "dead", value: "delete me" } ]
}

Test.assert_equals((synchonize(source_records, my_records)), output)          <- 'Brackets' missing

Javascript random tests completed, awaiting ruby ones :)

I don't see the updated ruby test cases?

the js solution will always be yours because it was created by editing the kata, which is fine :)

Sorry, it seems me saving the (ruby) kata, made your solution mine, even in Javascript. Can you 'touch' it again, so your nice js solve is owned by you again.
Thanks,
Mads

Added more solution text cases

Thanks, I can add some for ruby too

no worries, javascript version added. Will do random tests for javascript to resolve issue above for js, will still need you to do random tests for ruby

Yes, please do! Yeah, I think it started out with javascript and I pressed 'save' before I switched to ruby, sorry

Needs random test cases

it seems you've accidently submited the javascript version, I can translate the ruby code for the javascript version if you wish?

The javascript version is broken, there's issues with the template and the submit code
