var num = prompt("Give number");
function fact(num) {
var fact;
while(num>0){
fact *= num--;
num--;
}
return fact;
}
alert("Factorial is: "+fact(num));

Line 5 needs to be
var fact = 1;
so you don't start by multiplying by 0

Line 8 needs to be
fact *= num;
so you are multiplying "fact" by the current counter BEFORE you decrement "num" by 1
