Shouldnt there be a ; at then end of the promise chain?

I noticed in Guil's code there isn't a semi colon at the end of the catch/finally statements. Should there be?

No, in fact, using es2015 onwards you don't actually need to include a semicolon at the end of any of your lines of code in JavaScript. However there are some guidelines worth observing. Take a look at this article: https://medium.com/@thakkery/a-practical-style-guide-to-semi-colons-in-es6-c4f63d03a904

I think the correct answer is yes, it should, if you are typically ending all your relevant lines with a ;.

But as Kevin said, it's not mandatory. It's more of a stylistic choice I guess.
