In this example you dont really need word "return". Arrow functions which are one line and dont use curly braces automatically return result. So it should be like this:
const holidays = () => "Merry Christmas and a happy new year 😀!"

Actually, you said arrow functions don't have arguments.
That is false.

Oh, you meant the keyword (you should probably specify that in the post).
Yeah, I just added it now.
Thanks for the info. Looking for the continuation.
Small note: I think there is a typo for your first example Object methods. You mention "the property post.claps would increase by one". However, there is not property "claps" in the code example. There is "likes" though.
At any rate, good stuff here and thanks again for posting.

That's a good one.
cool stuff! Actually, I didn't know this 😍(before reading this post)
Glad it helped 😁
