I receive this error but I'm still trying to figure out the problem

there is a syntax error in your error which would create an error but during compile time which i would assume is not where you would like to throw that particular error :)

There is some problem to solve test (to raise an error) in JS , because just 'throw new Error('error)' doesn't works

After attempting this kata on Java i fail on the following

After applying rank of -1 the progress was expected to be 21, but was actually 20 expected:<21> but was:<20>

I have this code running in eclipse and it seems to pass every test i can think of, does someone know what im missing here or what the test case is?

EDIT: Never mind, I have solved my problem. thank you
