'for' loop between two numbers

It looks like I went to far and I don't know how to reel it in.

My Code:

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

The Challenge throws back this "The console should write out 4 the first time in the loop and 156 the last time through the loop."

And it looks like in the console it does 4 to 156 but in the last one after maybe 152 loops, I'm guessing.

Soooo... I may not be understanding the question.

This program generates a lot of digits, but they aren't numbers, they are strings. And because of concatenation each string printed out gets larger and larger.

But you're right, you can fix this just by simplifying. Your loop already runs from 4 to 156 with the loop variable "i". So what if you were to use the variable i as the argument to your console.log call? Then you could eliminate the "between" variable altogether.
