Question

var day = prompt("enter the day");

case 1:
document.write("Monday");
break;
case 2:
document.write("Tuesday");
break;
case 3:
document.write("Wednesday");
break;
default:
document.write("Another day");

Answer 1

Replace the cases as shown below:
case '1':
case '2':
case '3':
Since you are taking input using prompt it stores the input as a string rather than number......

OR

just write this statement
var day = prompt ("enter day");
day=parseInt (day);
.
.
.
.
.
This makes the variable day to store the input data as an integer rather than string.....

You Can use anyone one method which you feel easy......

Answer 2

Try it like this:

var day = prompt("enter the day",1);
switch (parseInt(day)) {
case 1:
document.write("Monday");
break;
case 2:
document.write("Tuesday");
break;
case 3:
document.write("Wednesday");
break;
// more cases here...
default:
document.write("Another day");
}
