Can I use "or" in a switch statement of javascript?

Question

Is the following syntax possible?

var x = prompt()
switch (x) {
case 1 or 2 or 3 :
document.write('abc');
break;
case 4 or 5 or 6 :
document.write('def');
break;
}

Answer 1

No, and neither you should do it this way, try using if-else statement instead, like

if([1,2,3].includes(x))
document.write("abc")
else if([4,5,6].includes(x))
document.write("def")
