Hello, welcome to lesson four, using JSX. This is a very exciting lesson. I'm going to show you how to use JSX to dramatically simplify the code that you write in React applications. So, in a nutshell, JSX stands for JavaScript XML. And what you can do is you can actually embed XML code directly into your JavaScript to make it easier to render the user interface. So you'll have, instead of having files called like some file dot JS, you'll have some file dot JSX. It'll contain JavaScript code for application logic, like if statements and loops and functions and such like, plus embedded it'll contain XML to represent the user interface. So when you want to render an h1 for example, instead of saying react. createElement h1, you can just say h1 using XML syntax and it gives you a much more concise syntax. So once we've covered JSX in this lesson, we will be using JSX forever into the future. So let's go!
