Thanks for the PR. I'm going to close this without merging as we don't need the extra scope of that article in that lesson. We only need to make a note about jQuery due to the questions we used to get asked a lot in the community. If someone wishes to explore jQuery and vanilla JS equivalents, they are welcome to do so in their own time but it's not something we intend on including in our curriculum, even as an additional resource.
