I have no idea, how to solve this challenge as I don't have idea about boolean primitive. I did google search, read hints but no avail? Would you mind, anybody?

It tells you in the second line of the instructions what a Boolean primitive is:

Boolean primitives are true and false .

There isn’t anything more to it than that, no further explanation is really necessary. Either the value true or the value false.

= in JavaScript means “assign the value on the right hand side to the variable name on the left hand side”.

It doesn’t mean “left hand side equals right hand side”.

Sometimes the simple ones can be puzzling.
The problem here is that you haven’t broken your work into two steps:

  1. Check if a value is classified as a boolean primitive.
  2. Return true or false .

try using an if else statement and return based on that.

Alternatively you can do it in one line but it requires the use of a trinary:
return typeof bool == ‘boolean’ ? true : false;

Hey Man! Update here, I did more of a google search & came back to your solution & got it. Basically we have to check whether the arg passed is boolean or not. Thanks for your time [your real name :sweat_smile:]
