  1. Nice article!

    Why do you still use class components? It’s 2020, function components with hooks are not an “alternative” way. They are THE way to go and classes are unnecessary for the examples you show.

    Your article is a great resource for beginner React developers, but also confusing, because you use class components.

    1. This post was originally published several years ago, before the stable release of the Hooks API, and we just updated it a few months back. We’ve added an editor’s note to clarify. Thanks for keeping us honest.

  2. Althought this article has inmense value and all of this is valid React, when an application gets big, using live vanilla javascript to condition the render adds complexity and you start building an enviroment very prone to errors later, good practice will be create a component that handles the condition taking it as a prop and returns the children or null, and reuse it across the app, making your render entirely declarative instead of imperative… has been an old trade in San Francisco since the begining of React.. truth is you can call it how ever you want,, but make sure the component do that.. back in the pre-hooks days ppl use to do it using a HOC ….
