Why is the third option is correct answer? If this is correct, it means that we can use other three forms of calling _num. Why do we can use console.log(tempObj[‘num’])? I see this form of calling first time. Why do we use square brackets here?
Why the last option is true? What is it, ‘js’?
I thought the third option was true. It is not a correct object literal?!
And why is the last option true? Why we use square brackets again? I thought we could write bikes.specialized = ‘red’?
I will be very appreciative to see your explanations
