Ruby Gotcha: Precedence of array insertion and or operators
This was a little bit surprising for me:
1 2 3 4 5 6 7 8 |
>> array = [1,2,3] => [1, 2, 3] >> array << nil || 8 => [1, 2, 3, nil] |
The correct way to do this is:
1 2 3 4 5 6 7 8 9 |
>> array = [1,2,3] => [1, 2, 3] >> array << (nil || 8) => [1, 2, 3, 8] >> |
