Second parameter in prompt mostly comes up as a placeholder like in HTML input tag!

Yeah but placeholder remains in background while the text in this case stays and we have to erase it to write anything...

the second parament can be an empty string like this ex. prompt("how are you today?", " "); because some browsers will put undefined if no second parameter is defined
