No random tests.

Is the version always 3 digits with dots? Can names contain digits? Etc... The format should be described better and a few tests with similar strings isn't enough.

The sample tests aren;t structured correctly, so they just print to stderr.

No random tests.

More random tests have been added now. Let me know if any other changes are still needed.

OK, I can see that happening. :]

That leaves mostFrequent(['p','p','p','p'], 'asd') and friends - "asd" is not an int.

And the input array element types all being changed to string? If it were specified in the description, it could be a feature instead of a bug. But it would need to be documented. I'd prefer not converting array elements myself.

Not finished yet! :] ( And Donald and I still want random tests as well! :] But get the specs and the fixed tests stable first. )

Looking good.

Now, those random tests ..

Thanks, updated.

I see now. Got carried away with edge cases.

Test.assertSimilar( mostFrequent( {a:1}, 1 ), [] )

And we were promised an array. That's not an array. Times four. :/

Please, fix the tests or fix the description. But this doesn't fit.

Also, I support Donald's request for random tests.

And I'd suggest Test.assertDeepEquals instead of Test.assertSimilar. ( That's undocumented, you couldn't really know that. But it's nicer, for arrays (and objects). )

Test.assertSimilar( mostFrequent( [1,2,1], 2 ), ['1','2'] )

Wot ?!?

Where did those strings come from ?!?

From an array, create a new array of a specified length with the most commonly repeated elements ordered first and all duplicates removed.
The function will be provided with an array and a limit. The array will be a list of strings, for example: ['a', 'd', 'd', 'b', 'e', 'd', 'e'] The limit will be an integer defining the length of

I'd make that

.. of a specified maximum length ..

and

.. defining the maximum length ..

Thanks, you're right. Not sure why I used splice.
