Why does this JavaScript code doesn't work

Question

function tvseries(teen,were,wolf)
{
alert(teen+ ","+were+" and "+wolf+" are your best tv series movies");
}
teen = prompt ("which is your first best series movie ");
teen = confirm ("are you sure");
teen = alert ("so go on");
were = prompt ("choose you second series movie");
were = confirm ("again are you sure");
were = alert("so continue");
wolf = prompt("choose your last best tv series movies");
wolf = confirm("at last are you deadly sure");
wolf = alert("you finshed your work here");
tvseries(teen,were,wolf);

/*It says undefined when you put input to the code it it a problem on argument or what*/

Answer 1

It's happening because you are overwriting the teen, were, and wolf value in alert and confirm.
