Tell us what’s happening:

totalCountPerProduct[dessert.id] = (totalCountPerProduct[dessert.id])+1 || 0;
    });

I just need to know what I did wrong, so that the challange is not being passed

Your code so far

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

The hint I am getting for your code above is:

“You should wrap your right-hand totalCountPerProduct[data.id] in parentheses.”

Which is not useful as you are already wrapping totalCountPerProduct[data.id] in parentheses. So I can understand your confusion.

The problem you are trying to solve here is that totalCountPerProduct[data.id] could be undefined, and so in that case you want to use the value 0 instead. So inside the parentheses you either want to use the value of totalCountPerProduct[data.id] if it isn’t undefined OR the value 0.

Hopefully that gives you enough of a hint as to how to solve this.

Can you paste your updated code in here so we can see what you did? Remember to use the method outlined above to paste it in here properly.

Matter of fact, I already solved the challange, understood that I had to state both facts and complete the expression.
Thanks your help
