bottom code snippet

This snippet: var i=0; // a `while..true` loop would run forever, right? while (true) { // keep the loop going? if (i<=9){ console.log( i ); i=i+1; } // time to stop the loop! else { break; } } // 0 1 2 3 4 5 6 7 8 9 Should be changed to this: var i = 0; // a `while..true` loop would run forever, right? while (true) { // stop the loop? if ((i <= 9) === false) { break; } console.log( i ); i = i + 1; } // 0 1 2 3 4 5 6 7 8 9
