السؤال 20

Spot the false classification of a value as falsy.

  1. NaN is falsy
  2. 0n is falsy
  3. The string "0" is falsyالإجابة الصحيحة
  4. The empty string is falsy

الشرح

The string "0" is nonempty and therefore truthy, so classifying it as falsy is incorrect. Numeric zero is falsy, but a string's textual appearance does not turn it into the corresponding number.
