Need help with challenge: Creating a 'for' loop that prints 4 - 156?

I am a bit confused as to how this isn't functioning properly. If I change the start number to '3' the individual numbers between 3 to 156 are printed to the log and the challenge yells at me saying the printed numbers must be between 4 and 156. However, if I change the starting number to '4' I get an error stating 'The console.log needs to print the individual numbers from 4 to 156 to complete the loop'.

script.js 
var num = ' ';

for ( var i = 4 ; i <= 156; i += 1){
  num = i + ' ';
  console.log (num);
}

You are adding a space to each number. The challenge only wants you to print the number.

for (var i = 4; i <=156; i++){
  console.log(i);
}

Ahhh... Thanks, I'll try that. One quick question about your answer: The ' i++ ' ? I haven't encountered that before? I'm going to guess it's another useful shorthand?

You put a space between console.log and the argument num. try this. var num = ' ';

for ( var i = 4 ; i <= 156; i += 1){ num = i + ' '; console.log(num); }
