At line one we create an array and bind it with the array
constant. Then the type of the value of this constant is evaluated by the typeof
operator.
There’s no such type as array
in JS, so it’s impossible to see the message ARRAY!
on the screen. In fact, all JS arrays are objects, so the execution goes into the else
branch, and SOMETHING WEIRD
is printed on the screen.
ANSWER: SOMETHING WEIRD
will be logged to the screen as all JS arrays have the type object
.
