can somehow explain the project because I don't really understand it, I was just following up

Oh man. I am so glad to see others struggled with this one too. It made no sense to me and the steps were HORRIBLE written. Thanks for posting this.

Thank you
at some point, the error "Cannot read property 'push' of undefined" occurred and it is not clear why

Thanks!
I was struggling for this one for a long time

Thanks, simonblakemore.
I too was getting "cannot read property 'push' of undefined" error. And couldn't get past it after spending too much time on this. As a last attempt, reset the project to start again and closely follow the instructions, only to run into the same error message again. Comparing my code to yours, I could see a couple of differences, but not to a degree where it woul be a factor (a semi colon here and there, a coma, and this line: this._courses[courseName].push(dish); I had as this._courses.[courseName].push(dish) -period before the opening bracket.
This project was more challenging than I expected

Even after reading the code solution, it's hard to understand the meaning of all steps, i wish they could they had explain it a bit more...
And why not to use classes object here ?

This was so crazy. Imagine taking your time, referring to previous object lessons before the project to make sure you did not miss something. At some point I had to ask myself if I had tried all I could. Went on the forum as well and still could not understand why the"push method on dishes" was throwing a flag. Just glad to know I was not running crazy when I saw the comments here @simonblackmore thanks for this.

Thank you!!!

This particular project on code academy was terrible. Lol.
