JS while... do... question

Why will this loop run only once? To me, it should do 10 times... x=0; do{ x++; }while(x>=10);

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

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.
