In the first line, we define the variable str and initialize it as a string with the value 1.

In the second line, there are two typecasts, first !str gives us false and then +false converts boolean into a number 0.

Eventually, in the third line, the typeof operator looks up the current type of str which is number.


ANSWER: string number will be printed to the console
