Updated my site to use https and @js_bin on my React tutorial (408k views so far) is down. Contacting support. Sorry pic.twitter.com/H0GYlLPyjM— Shu Uesugi (@chibicode) October 22, 2017. Written in July 2015 by Shu Uesugi. (Updated Jul 15, 2016): Updated for React 15. This page is no longer being updated as I don't have time :( Also Twitter changed the logic so photos no longer count towards character count. I also heard React.js was good and recently spent some time playing with it. Now that I'm pretty comfortable with React, I decided to write a tutorial on this subject.

Your solution does not work because it doesn't make sense logically. The error you receive may be a bit vague, so let me break it down. The first line states:

Cannot update during an existing state transition (such as within render or another component's constructor).

Whenever a React Component's state is updated, the component is rerendered to the DOM. In this case, there's an error because you are attempting to call overflowAlert inside render, which calls setState. That means you are attempting to update state in render which will in then call render and overflowAlert and update state and call render again, etc. leading to an infinite loop. The error is telling you that you are trying to update state as a consequence of updating state in the first place, leading to a loop. This is why this is not allowed.

Instead, take another approach and remember what you're trying to accomplish. Are you attempting to give a warning to the user when they input text? If that's the case, set overflowAlert as an event handler of an input. That way, state will be updated when an input event happens, and the component will be rerendered.

Question: What do React.createClass and ReactDOM.render do? Do I need to understand them now? Answer: Don't worry about it for now. Basically, React.createClass creates a piece of UI with a name (in this case, TweetBox). This then gets attached to the DOM through ReactDOM.render(<TweetBox />, document.getElementById("container")) - meaning this UI is added inside the <div id="container"> tag. That's all you need to know for now. Question: Do I need to do anything special to write JSX on my local machine? Answer: Yes, but that's outside the scope of this tutorial - in short, you need to import something called JSX transformer (here's how). This step is not necessary on JSBin though. All you need to do to write JSX on JSBin is to (1) add a React library (the one without addons) from the dropdown and (2) select "JSX (React)" from the dropdown menu on the JS view. Question: Isn't it a bad style to write markup (HTML) and behaviors (JS) in the same place? Answer: It might be a bad style for simple web pages, but not necessarily so for large web applications. In large web applications, there will be hundreds of pieces of UI, each containing its own markup and behaviors. The code will be more manageable if those markup and behaviors are kept together for each piece of UI, as opposed to keeping "all markup" together and "all behaviors" together. And React is designed for developing large web applications. In fact, React was actually created and used by Facebook, one of the largest web applications ever. Next, I'll show you how to write the above React code step-by-step.
