Does the log to console need to be outside the loop?

Am I able to have the console.log within the loop rather than outside the loop? The example in the lesson uses document.write and places that outside the loop. If I did that I would know what to put within the {}. Any help is appreciated.

script.js 
for ( var i; 3 < i < 157; i+=1 ){
  console.log(i);
}

you just need to assign the loop variable directly to 4.

for ( var i = 4; i < 157; i+=1 ){
  console.log(i);
}

If you wil put log after the loop,you will get an error.Because you only able to use 'i' variable inside the loop,it is loop's counter.
