سؤال 4

Classify the statements about JavaScript functions and typeof. Select all that apply.

  1. typeof applied to a declared function produces functionپاسخ درست
  2. A function value makes typeof produce object
  3. typeof applied to x => x + 1 produces functionپاسخ درست
  4. The typeof result proves function is a primitive type

توضیح

Applying typeof to a callable function object produces the string function, even though the value is still an object rather than a primitive. The claims that it produces object or creates a primitive function category each mistake the operator's label for the value model.
