A single line of JSX/JavaScript is dissected to reveal a subtle operator precedence bug. The expression `shouldNotShow === false > 0` evaluates in a non-obvious order: `false > 0` is evaluated first (due to `>` having higher precedence than `===`), then `===` compares `shouldNotShow` to that result, and finally `&&` combines it with `arr?.length`. The code happens to work by accident, but the correct and readable equivalent would simply be `!(arr?.length && shouldNotShow)`.
