Build a Library NaN instead of a number


I am having trouble figuring out what I am doing wrong in this project as the result it gives me is Nan and not a number? Any help welcome!

Hi there.

You have a typo in your getAverageRating() function. :slight_smile:

Fairly sure your ratings array doesn’t have a property called “legth”. :slight_smile:

Oh haha, you’re right! Thanks for pointing this out. Works ok now!

No problem. Sometimes the little errors are the hardest to spot on your own, especially if you’ve been staring at the same code for a while. :smiley:
