Why did this code output 60 and not 50?

Question

var x =10
x*= 2
while (x<30) {
x+= 5
y=x
}
alert(y+x);
I want to know in details if possible

Answer 1

20<30 is true so now inside while x=x+5 so x becomes 25 and y is also 25 since y=x.
Now 25<30 is again true so now inside while x=x+5 so x becomes 30 and y is also 30 since y=x.
Now 30<30 condition fails and the loop is terminated. Now both x and y are 30 so x+y=60.

Answer 2

So the loop doesn't stop unless the certain condition is achieved. Now I know where I did wrong, I looped once which gave the output 50.

Avinesh thanks.

Answer 3

Because the loop broke when x = 30 and when y = 30
