TypeError: menu.addDishToCourse is not a function

Hey, @blorena. Welcome to the forums!

This is the error you’re getting, right? There’s a small typo in the method name.

While declaring the method, you have named it as addDishtoCourse and while calling the method, you’re using the name addDishToCourse and that’s why you’re getting the error!

It’s a very subtle typo and sometimes typos like this slip in without us noticing. Always double check the name of the method you’ve declared and the name of the method you’re calling.

Does that help?

EDIT:

A TypeError usually tries to inform us that we’re trying to do something with a value that is not allowed.

You’re trying to call a method which was never created. And that is not allowed, hence you see the error.
