javascript - While loop inside while loop [Javacript] -

how use while loop inside while loop without executing next loop (from outside while loop) unless inner while loop done executing?

var x = 0; var y = 0; while(x < 10){    while(y < 10){       console.log(y);       y++;    }   x++; } 

i'm guessing problem here @ end of inner loop, y set 10 , never reset 0. try instead:

var x = 0; var y = 0; while(x < 10){    while(y < 10){       console.log(y);       y++;    }   y = 0;   x++; } 

otherwise, once inner loop finishes once, never runs again.
