Yes, it's much faster by using map in class property to store alrady found numbers.
Thanks for the feedback.

Also for me :/

In the first unit test for Java, the expected and actual paramaters of assertEquals are swapped.

@Test
public void test() {
	assertEquals("toJadenCase doesn't return a valide JadenCase String! try again please :)", jadenCase.toJadenCase("most trees are blue"), "Most Trees Are Blue");
}
