Question 24

What does the expression 0 || "ready" evaluate to?

  1. 0
  2. readyBonne réponse
  3. true
  4. false

Explication

The logical OR operator skips the falsy zero and returns the first truthy operand, which is the string "ready". Returning boolean true would be incorrect because this operator preserves an operand value rather than always producing a boolean.
