while loop if one of data block condition met

Question

I am doing something like:
var y=[1,2,3]
var x=prompt("what is the number?");
while(x!=y){ /* what I am trying to do is if x does not include any value in y, the while loop will occur. but this line will only make us needed to input all the values in y to come out from this while loop... how should I do this....? */
alert("That's not right!");
var x=prompt("what is the number?");
}
alert("Good job!")

or this is not possible and i should use switch loop instead of while loop?

Hi. Your "while" is okay for making a loop, but your condition is incorrect. "y" is an array of numbers and it is not right to compare a number with an array, so you need something like a "find" function to determine if "x" is inside of an array or not.

A working code sample:
var y=[1,2,3];
var x=prompt("what is the number?");
while(x!=y.find(n => n == x)) {
alert("That's not right!");
var x=prompt("what is the number?");
}
alert("Good job!");

or you can you an alternative version:

while(y.indexOf(x)!=-1) {
