Thank you.

script.js 
var counter
for (var i=4; i<=155; i += 1) {
  console.log( counter );
}

For each iteration of the for loop you need to print the value of i , since it is the variable getting updated in for loop. But instead you are printing the value of counter which has the value undefined.

// with counter variabe
for(var counter=4;counter<=156;counter++) {
    console.log(counter);
}

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