Replacing $ lookup with $ graphLookup in chapter 3 lab (using $ lookup)

My original solution:

workaround with $ graphLookup:

@marcobl there are other course takers working on the same labs as you and as a result it’s against forum guidelines to post full or partial solutions to labs. Suggest you delete your post.

There are posts already stating the equivalence between $lookup and $graphLookup under certain conditions. Here’s one such post.

Hi @marcobl,

Your observation and query are correct here. However, I have deleted the queries as it contains answers.

Please feel free to reach out if you have any questions.
