why the output 6 i`m not understanding

Question

var x = 0;
while(x<6) {
x++;
}
document.write(x);

Answer 1

Loop after loop, x is incremented by 1. When x is 5, 5 is lower than 6, so we enter the loop yet again, in which x is incremented to 6. Then we exit the loop because 6 is not lower than 6, and we print 6.
