Documentation Writes a Paragraph to Avoid Saying 'Callback'

Level 1: Just Say the Word

Imagine asking someone where the bathroom is, and instead of pointing and saying "down the hall," they hand you a three-page essay titled "A Powerful Mechanism for Personal Relief: Navigating Interior Spaces in the Modern Home." All you needed was one word, and they gave you a lecture that somehow never includes it. That's why the character in the green shirt is shouting at his screen — the instructions he found use a hundred fancy words to dance around the one simple word every programmer already knows. The frustration is universal: nothing is more annoying than someone explaining around the answer instead of just saying it.

Level 2: What the Docs Were Trying to Say

The missing word, defined: a callback is a function you hand to another function, to be executed later — typically after some operation finishes. It's one of the first patterns you meet in JavaScript: "do this, then run this."

In the snippet on the monitor, setState() is the classic React class-component method for updating a component's state (the data that drives what's rendered). State updates in React are asynchronous — React batches them for performance — so you can't just read the new value on the next line. That's why setState accepts a second argument: a callback that React invokes only after the state has been applied and the component re-rendered. The entire highlighted paragraph is a long-winded paraphrase of one sentence: "the second argument is a callback that runs after the update."

If you're early in your career, this comic is a preview of a daily experience: you search for one specific fact, and the top results bury it under introductions, conclusions, and "in today's fast-paced development landscape" padding. Learning the standard vocabulary — callback, promise, closure, memoization — is your defense. Jargon gets a bad reputation, but it exists for exactly this reason: one precise shared term beats four sentences of approximation.

Level 3: A Powerful Mechanism for Saying Nothing

WebDevToons #242 captures a very specific modern documentation pathology. The screen in panel one shows a perfectly ordinary React snippet — this.setState({ isLoggedIn: true }, () => { console.log('User is logged in.'); }) — followed by a highlighted "Conclusion:" that reads like it was paid by the word:

"The second argument of the setState() function in React.js provides a powerful mechanism for handling state updates and executing code after the state has been updated and the component has re-rendered..."

The character's eruption — "WHY CAN'T YOU JUST SAY `CALLBACK`?!" — is the punchline, but the real target is the entire economy that produces prose like this. Experienced developers recognize the house style instantly: it's the dialect of SEO content farms and, increasingly, of AI-generated tutorials. "Provides a powerful mechanism," "ensure predictable behavior," "streamline the development of complex user interfaces" — these phrases are engagement ballast. They exist to pad word counts for search ranking, not to transfer knowledge. The one word that would compress the whole paragraph into something a developer can index in their brain — callback — is the one word the text refuses to use, possibly because the author doesn't know it, possibly because a model was prompted to "explain thoroughly," possibly because precision doesn't rank.

There's a second, subtler joke for React veterans: the documented API itself is a fossil. The class-component this.setState(updater, callback) form belongs to an era before hooks; modern React steers you toward useEffect for post-render reactions, and the second-argument callback has spent years in "supported but please stop" territory. So the comic's hapless reader isn't just wading through verbose filler — they're wading through verbose filler about a legacy pattern, the classic fate of anyone googling an error message and landing on a 2019-flavored tutorial dressed in fresh SEO clothing. Documentation has always had two failure modes: terse man-pages that assume you already know everything, and this — a warm bath of words that assumes you know nothing and ensures you learn nothing. The industry spent decades complaining about the former and then automated the production of the latter.
