 ### Classes confuse both people and machines
 
-In our observation, classes are the biggest barrier to learning React. You have to understand how `this` works in JavaScript, which is very different from how it works in most languages. You have to remember to bind the event handlers. Without unstable [syntax proposals](https://babeljs.io/docs/en/babel-plugin-transform-class-properties/), the code is very verbose. People can understand props, state, and top-down data flow perfectly well but still struggle with classes. The distinction between function and class components in React and when to use each one leads to disagreements even between experienced React developers.
+In addition to making code reuse and code organization more difficult, we've found that classes can be a large barrier to learning React. You have to understand how `this` works in JavaScript, which is very different from how it works in most languages. You have to remember to bind the event handlers. Without unstable [syntax proposals](https://babeljs.io/docs/en/babel-plugin-transform-class-properties/), the code is very verbose.

The distinction between function and class components in React and when to use each one leads to disagreements even between experienced React developers.
 
 Additionally, React has been out for about five years, and we want to make sure it stays relevant in the next five years. As [Svelte](https://svelte.technology/), [Angular](https://angular.io/), [Glimmer](https://glimmerjs.com/), and others show, [ahead-of-time compilation](https://en.wikipedia.org/wiki/Ahead-of-time_compilation) of components has a lot of future potential. Especially if it's not limited to templates. Recently, we've been experimenting with [component folding](https://github.com/facebook/react/issues/7323) using [Prepack](https://prepack.io/), and we've seen promising early results. However, we found that class components can encourage unintentional patterns that make these optimizations fall back to a slower path. Classes present issues for today's tools, too. For example, classes don't minify very well, and they make hot reloading flaky and unreliable. We want to present an API that makes it more likely for code to stay on the optimizable path.
