:warning: Be careful about testing a challenge in an external REPL, workspace, or browser.

If you have misunderstood the challenge, it's also very likely that you will misinterpret the results.

In this case, the challenge is expecting you to call console.log from inside the loop, once for each number.

You also won't need any HTML tags, just log the number.

Are you sure it's not looking for...

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

When doing what you've posted in your browser, while it works, it's not printing the numbers themselves to the console. It's printing a string variable with each number wrapped in it's own div container.

The following runs using atom but not is not accepted as an answer in the code challenge (create a loop that numbers...). feeling quite annoyed. var counter = 0

for (var counter = 4; counter<=156; counter +=1 ) { console.log(" " + counter + " "); } Sincerely, what am I missing?

You're not exactly "missing" anything. But those extra spaces you are wrapping your values in are confusing the checking mechanism. You don't need them anyway, since log messages will each appear on a separate line.

As I told David, "just log the number".
