f value can exceed the di . Then there is no stoping loop. Use >= instead of == , in if condition. And no need to print d again out side loop.

function main() { var di = parseInt(readLine(), 10); var s=0 var f; var d=0; do{ d=d+1 f=s+7; if (f >=di ){ console.log(d) break; } s=f-2; }while (s!=di); //if (s==di){console.log(d)} } See if you use if( f==di) break ; Then what if example di = 30 but f = 34 , you should break the loop as it reaches depth already. But f==di is not true so it won't stop loop and s!=di (32!=30) is true so it continues loop so never after f==di comes true. Then it is infinite loop. You must use condition if( f >= di) break; And if you print day value before break then no need to print after loop. Of course if condition is false though. So Never print I think.

Side note: get used to using meaningful variable names. They help a lot in debugging.
