I've been given a task that I have pretty much solved myself but there is some small correction that needs to be made and I need a help from someone to point me out of where to make some cosmetic changes to my code:
Here is the Task:
Transform the multi-condition if statements sample code into a switch sample code.
var myAge = parseInt(prompt("Enter your age", 30), 10);
if (myAge >= 0 && myAge <= 10) {
document.write("myAge is between 0 and 10<br />");
}
if (!(myAge >= 0 && myAge <= 10)) {
document.write("myAge is NOT between 0 and 10<br />");
}
if (myAge >= 80 || myAge <= 10) {
document.write("myAge is 80 or above OR 10 or below<br />");
}
if ((myAge >= 30 && myAge <= 39) || (myAge >= 80 && myAge <= 89)) {
document.write("myAge is between 30 and 39 or myAge is " + "between 80 and 89");

<title>SOME CODE</title>

</html>So the Result by Default under the age 30 is:
myAge is NOT between 0 and 10 myAge is between 30 and 39 or myAge is
between 80 and 89
Here is what I'm done so far:
var myAge = parseInt(prompt("Enter your age", 30), 10); // Get the user's response, converted to a number
switch (true) { // Switch statement if the condition is True
case myAge >= 0 && myAge <= 10: // Check the inputs value in range 0 - 10
document.write("myAge is between 0 and 10<br/>");
break;
case (!(myAge >= 0 && myAge <= 10)): // Check the inputs value if it's not a in range between 0 - 10 ( !(myAge >= 0 && myAge <= 10) )
document.write("myAge is NOT between 0 and 10<br/>");
break;
case myAge >= 80 || myAge <= 10: // Check the inputs value if it's greater/equal to 80 OR less/equal to 10
document.write("myAge is 80 or above OR 10 or below<br/>");
break;
default:
document.write("myAge is between 30 and 39 or myAge is " + "between 80 and 89"); // Check the inputs value in range 30 - 39 And 80 - 89
}<DOCTYPE html>

</head>
<body>
</body>
</html>And, as you can see that the result is slightly different. I got printed just this:
myAge is NOT between 0 and 10
I know the solution is simple anough BUT unfortunately I cannot solve it so that it will print a:
myAge is NOT between 0 and 10 myAge is between 30 and 39 or myAge is
as well.
Please, someone, help me so sovle it I would really apreciate it!
