Would this not work?

I keep getting this error "You need to log out EVERY number from 4 to 156 to the console. Your loop calls the console.log() method 152 times." this course seems to be very challenging and I am having issues knowing what I am suppose to do. I have yet to have a work space work the way it is suppose to when i follow along. Could it be from using let instead of var?

script.js 
for ( let i = 1; i <= 156; i += 1) {
  if( i > 4 ) {
      console.log(i);
     }
}

The test "i > 4" doesn't include 4, so that will be missing from the output.

But an even better way to do this would be to initialize "i" to 4 in the loop, and then you don't need the test at all.

Initialization is the first of the 3 clauses of a "for" loop:

for (let i = 4;                    <-- initialization
                i <= 156;          <-- condition
                          i += 1)  <-- increment
