for loop in task works for me but the website says it's wrong

Hi everyone. I am stuck in the for-loop task. It says to print out the numbers 4 to 156 in the console. This is my code and it runs perfectly fine, when I test it:

var number = "";

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

But the Website says it's wrong. I am lost. What is wrong with it? Can anyone help me?

script.js 
var number = "";

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

It seems that you have some extra codes that don't need to be there. You do not need the number variable, nor the addition number + i in the console.log.

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

This is all the challenge is asking for.

It's probably because you're printing them as a string not as a numbers. When you declare var number = "" you say that this is a string, so all numbers added there are strings as well. If you go and do var number = 0 and then add to it, the challenge should work.
