Screenshot of my tests Output

For me its test4 not test5 .See image above

Maybe you are right ,maybe there is a bug in my code , but please just take a look at it.Thanks a lot

I know but from the description is says
If a or b are nil (or null or None), the problem doesn't make sense so return false.
If a or b are empty the result is evident by itself.

b is giving me null ,so how come its expecting true ??

Failing 4th Basic test in javascript even though when i console.log the input
Log
Array1 = [] Array2 = null
and it says
Expected: true, instead got: false
clearly its supposed to return false .Te rest of the test pass.

when i run tests they all pass but when i try to submit it reurns
Unknown error
Process took 6067ms to complete.

is it the server or problem with my code ?
