Why the answer is 8 please ??? I don't understand :'(

Question

What is the output of this code?

var x = 3;
switch (x) {
case 1:
document.write(x);
break;
case 2:
document.write(x+2);
break;
default:
document.write(x+5);
}

ANSWER: 8

Answer 1

Because it will check if x is 1 and then if it is, it will write the value x.
Right now it isnt 1 nor 2. So it goes to the default case

Answer 2

Because you have defined a switch and the first case is 1.
It will check if it is 1

Answer 3

switch value of variable <x>
Is it 1?
If it is then print <x>
Break out
Is it 2?
If it is then print <x> plus 2
Break out
Otherwise
print <x> plus 5

Knowing <x> value is 3, the first two evaluations was proven wrong (false). And since there are no other conditions to check against value of <x>, we end up in the "Otherwise" block.

Answer 4

Thank you for your answer but I still don't understand i'm sorry. And why 1 now ? :'(
