Need help with for loop code challenge.

The Challenge: 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.

Here is my code. Did i miss something? Thanks for your help!!

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

script.js 
var num;
for (i = 4; i <= 156; i ++1) {
num = i + “number”;
}
console.log(num);

Ok so i did the challenge and here is what i did to make it work

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

There is a few things on your code that is causing it to crash. The main thing is you have i that increments plus one but you also have 1 after the two ++ which is not needed.

And the other thing is for what they are wanting they just want you to log to the console in the for loop it self.Hope this helps if you have further questions let me know.

Repost of my original comment...

Hello Val,

One of the problems with your code is that you have created more variables than is necessary for this program. It is important that we keep our programs as simple as possible.

So we can take your code and do this:

var  num;
for(num = 4; num <= 156; num++) {
    console.log("Number " + num);
}

You could also have written it this way:

for(var num = 4; num <= 156; num++) {
    console.log("Number " + num);
}

Do you see how that fixes your problem and where your errors were?

Cheers

Franciscus

Thanks guys!!! I will try your suggestions. I think I have a tendency to over think what is being asked. Before I got to this code, I had more than one variable applied. :) So, really appreciate you taking the time to explain!
