I agree I believe this is badly named, for it truly to be a useful camelcase transform
First letter of the whole string should always be lower case.
Every other new word should be upper case
Every other letter should be lowercase
As the tests don't test that other letters are lower case i.e. there is no test for the-steAltH-WarrOr
Many of the solutions while currently correct under the decription and tests above are not overly useful for enforcing camel case.
