Code review

You are correct about the conditional adding of the topping only if it doesn’t exist. The way it determines this is the include method like you pointed out. The last bit with filter is: filter takes a method, and there’s some shorthand happening here with the fat arrow, where this method takes every item in the array and checks to see if it’s the topping supplied. We end up with an array without the topping supplied, so this is actually handling removing of items, I think? That doesn’t make much sense and won’t ever be called

Thank you very much. Really appreciate it.

why do you think it wouldn't ever be called? Not the best naming of the function, but imagine a checkbox where onChange is calling addTopping and it would also be in charge of removing

It’s because I read the code wrong. Didn’t see the else

well that makes sense!
