 Now, one of the coolest things about React is that we can define our own components and those components are just functions. That's correct. They are just functions. So, if we wanted to use this all over the place and use it like this as greeting, we just wrap it in a function. So, we'll call this function greeting. No arguments here and return this hello React H1. Now, it's approved that I don't have anything up my sleeve. I'm going to use that older function declaration syntax to do the same thing. Function greeting. We'll have a block. The returns are H1 with hello React. And close that up. Good to go. Now, I like this kind of newer, more terse syntax a little bit better. So, let's stick with that.
