You have to look at the error itself. When I run your code it reads

return this._courses[courseName].push(dish);
TypeError: Cannot read property 'push' of undefined

That should be a good clue. Consider, what value is this._courses[courseName] giving you? Try console.log on that value before the return line to get a better idea.


Thanks for responding. It says undefined when I console.log(this._courses[courseName]), so I reckon something is wrong in that its not recognising the this._courses[courseName] as being equal to the arrays underneath _courses.

Still can’t figure it out though :frowning:

Took a look at the code. The .push() error for undefined is because… well, nothing is defined! Pay attention to typos.
You have:

let menu = {
 _courses: {
   appetizers: [],
   mains: [],
   desserts: []

but when you add dishes you have:

menu.addDishToCourse('appetizer', 'Cutlets', 0.3);
menu.addDishToCourse('main', 'Biryani', 4);

Did you spot the difference?


this._courses.appetizers throws this TypeError: Cannot read property 'appetizers' of undefined

So it’s helpful to go down the rabbit hole of checking that all your parameters are logging as you want them to be logging. It may seem tedious, but it’s a common process that’ll make you stronger as a programmer.

Thanks so much once again bro, you are correct I did what you said and finally found the error!

Since the program does not use the getters or setters we don’t see the circular reference error.
