console.log(array1, array2);

Hello. I can't pass 8th of basic test (Expected: false, instead got: true).
How can I view the source data of this one? In random tests all data is available, but there is no in basic tests.

a or b might be nil or null or None (except in Haskell, Elixir, C++, Rust, R, Shell).

I keep on receiving an error on the 5th of the basic tests. It keeps saying "Cannot read property 'map' of null".
