in the video, he wrote
var message = "<p>" + topNumber + otherStuff + ".</p>"
What is the purpose of the paragraph tags in quotation marks? Is it necessary? If so, why?

The thing is as long as it's a string, should be surrounded with commas. Just another example. document.write("<h1>Hello my Dear friend! I hope everything is OK!</h1>"); or document.write("<h1>Hello my Dear friend! I hope everything is " + exampleVariable + "</h1>

Loris Guerra
17,536 PointsThat's because the "document.write()" method expects a string as augument in order to render something to the browser. For this reason you need to wrap your HTML code using quotes.

Tom Oesterman
Courses Plus Student 8,889 PointsYou do not need the period before the closing paragraph tag. The instructor included the period to end the displayed sentence. It has nothing to do with the code.
