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.

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
