What's the difference between using the Criteria shown in the video or adding more andWhere statements?

Is it just Criteria can be reused in other queries easily part?

Hey @Alex123

In this case, it is convenient to use a criteria because you can filter the fortuneCookies collection without relying on the repository. You can just say $category->getFortuneCookiesStillInProduction() in any place of your code, and it will make a DB query under the hood

Cheers!
