-The easiest way to get started with React is to use [this Hello World example code on CodePen](codepen://hello-world). You don't need to install anything; you can just open it in another tab and follow along as we go through examples. If you'd rather use a local development environment, check out the [Installation](/docs/try-react.html) section.

 The next few sections will gradually introduce you to using React. We will examine the building blocks of React apps: elements and components. Once you master them, you can create complex apps from small reusable pieces.
 
-## A Note on JavaScript
+## Knowledge Level Assumptions
 
-React is a JavaScript library, and so we'll assume you have a basic understanding of the JavaScript language. If you don't feel very confident, we recommend [refreshing your JavaScript knowledge](https://developer.mozilla.org/en-US/docs/Web/JavaScript/A_re-introduction_to_JavaScript) so you can follow along more easily.

If you don't feel very confident, we recommend [going through a Javascript tutorial](https://developer.mozilla.org/en-US/docs/Web/JavaScript/A_re-introduction_to_JavaScript) to check your knowledge level and enable you to follow along this tutorial more easily.
 
-We also use some of the ES6 syntax in the examples. We try to use it sparingly because it's still relatively new, but we encourage you to get familiar with [arrow functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions), [classes](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes), [template literals](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Template_literals), [`let`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/let), and [`const`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/const) statements. You can use the [Babel REPL](babel://es5-syntax-example) to check what ES6 code compiles to.
