Interesting kata! Actually, I can rarely say this, but it's pretty simple, in my opinion. Maybe I took not the most effiecient way to solve it, but it's straightforward.

2 hours 😅

This was an interesting problem. I took a longer, slower path, writing down the logical process on a paper.

Solving this using JS. Pass the the basic tests. Then when I hit "Attempt", I pass all of the 50 random tests but fail the basic test that wasn't there before. The new basic test is expected '0' to equal ''. I adjusted my code to address this too, but the test issue persists. The code works as intended in the firefox console. Any suggestions for the beginner?
