What is this not working?

Why is this for loop method not working? When I place this into my own browser it gives me all the number from 4-156 but in this work station it isn't.

script.js 
var yes = '';

for (var i = 4; i <= 156; i += 1) {
    yes += i + ' ';

}
console.log(yes);

Hi there,

When I try to run this in the challenge, it gives an error about console.log only being called once - this seems to indicate that the code for checking your answer is specifically looking for you to call a separate console.log for each number - meaning each should be on its own line in the console. With some modifications, we can make this work for your code - basically, you can bypass the 'yes' variable entirely, and just console.log using the i variable inside the loop. It would look something like this:

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

Thank you very much. :-) That makes sense I guess I wasn't understanding the wording of why it was coming up wrong.

No problem - it can definitely be tricky at times!
