Creating a for loop in JavaScript

Challenge Task 1 of 1

Create a for loop that logs the numbers 4 to 156 to the console. To log a value to the console use the console.log( ) method.

Can someone help please as there is an error in my code somewhere??

script.js 
var spin = '';

for ( var i = 4; i <= 156; i +=1 ) {
  spin += '<div>' + i + '</div>';
  console.log(spin);
}

Hi Elizabeth,

Your code is logging html strings to the console instead of numbers. To output the numbers, simply log them directly to the console within the for-loop:

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