done

Looks great, thanks!

Looks great thanks!

...length of the longest prefix common to both strings....

I was also caught out like that initially.

In the JS verion, it would be nice if you would add a description to your final tests. Otherwise theres no feedback as to why any of the final tests are failing.

eg: Test.assertEquals(stringSuffix('ababaa'),12, "ababaa");

In the JS version, can you not just use Test.assertSimilar(...); in the example test cases?

eg: Test.assertSimilar(number(["a", "b", "c"]), ["1: a", "2: b", "3: c"]);

Nice Julz

Agreed, have updated the description.

Thanks, have added further test cases

Thank you, I have added more tests including a random string

Interesting way of getting arounnd the 'Bananas from Bahamas' test!

suggested initial tests cases

testArray('Testing Valid Values', 'should ignore non-zero numbers', squeakyClean([1,2,3,0,1.1]), [1,2,3,1.1]);
testArray('Testing Valid Values', 'should ignore non-empty strings', squeakyClean(['hello', '14', '']), ['hello', '14']);
