Good Day Jenniffer, The Semi Colon whether used or not will not really effect the way your code runs, in "MOST" instances, however in my brief experience with coding , I personally find that its easier to read my own code , to better understand where my code breaks are. Some say "Yes Use it" others say "No It's not necessary", I say if your code is accomplishing what you set it out to accomplish use the method that best fits your coding style. Here is some information I found to be a "good 11 min. listen" on the Semi Colon subject topic. Happy Coding Ms. Hernandez. :-)

You will not get any error if you don’t put the semicolon.

Yeah, I think this was probably just a typo. Typically, you'll want to end return statements with a semicolon. Often, developers use an extension like Prettier to catch those things. But, Tammi Carter is correct, in this instance it won't affect behavior, but in other cases it might...so it's better to err on the side of caution.
