JS while... do... question

Question

Why will this loop run only once? To me, it should do 10 times...

x=0;
do{
x++;
}while(x>=10);

Answer 1

x never goes above 2
your condition says while x is greater or equal to 10

x starts as 0
the loop is executed once, incrementing x to 1 and then exits when the condition is not met

Answer 2

yes. of course. it's so obvious. while executes as long as it's true. here it's never true and that's what confused me. thanks.
