Greetings sir, I really appreciate you what you been in my coding journey. I haven't met you before but it seems to me like you are my old friend and your teaching skills is wonderful.
I really don't know while the particular exercise 14j solution is not removing the class list 'is-editing-quantity'. Please someone should help me because I have been stuck here a week now😭

My suggestion is: try use console.log(container) to check if the container able be found by the query selector.
if it could not be found, probably you might be forget to add the following element in the Save tag
data-product-id="${matchingProduct.id}"
