React's Official Decree on Component Terminology

Level 1: Soda, Not Pop

Imagine you’re at a friend’s house and you ask for a “pop” to drink, and your friend’s parent chuckles and says, “In this house we call it soda, not pop.” 😜 It’s basically the same fizzy drink, but they have a family rule about what word to use. It’s a tiny, funny difference in wording. The React meme is just like that, but for computer programmers. The people who make React are gently saying, “Hey, we like using one special term instead of a slightly different word.” It’s kind of silly-funny because it shows how even smart grown-up developers can be a bit like a picky family about the words they use. They’re all in on the joke that this little naming rule is a thing. Essentially, the tweet is playful: it’s reminding everyone of the “house rule” in the React family — use the word “function” when talking about these components, not “functional.” It’s a friendly nudge, and people who write code find it humorous because it’s so relatable. Just like calling a soda “pop” might get a lighthearted correction in some families, calling a React component “functional” gets a joking correction to say “function component” instead. It’s all in good fun and helps everyone speak the same language!

Level 2: What’s in a Name?

Let’s break down the joke for those newer to React or frontend humor. React is a popular JavaScript library for building user interfaces, and it uses the idea of components — reusable pieces of UI. There are two common ways to write a React component: as a class component or as a function component.

• A class component is written using a JavaScript class (an older style in React). For example:

  class Welcome extends React.Component {
    render() {
      return <h1>Hello, {this.props.name}</h1>;
    }
  }
  

  Here Welcome is a class with a render method that returns some JSX (React’s syntax for UI).

• A function component is written as a plain function that returns JSX, like so:

  function Welcome(props) {
    return <h1>Hello, {props.name}</h1>;
  }
  

  This accomplishes the same thing but with simpler syntax. Originally, these were sometimes called “functional components” in conversation because they’re made of functions.

So why is the React tweet saying call it function instead of functional? It’s about naming conventions – basically, agreeing on consistent terminology. In React’s official documentation and community guides, the preferred term is function component. The word functional can be confusing here. In general programming, “functional” refers to functional programming, a style where you avoid changing state and rely on pure functions (no side effects). However, React function components aren’t limited to that style – especially after React introduced Hooks. With Hooks, a function component can have its own state (useState) and perform side effects (useEffect for data fetching or subscriptions). In other words, React function components are not purely functional in the academic sense; they’re just components defined with functions.

Calling them function components (noun form) keeps things clear: it’s a component that is a function. Saying functional component (adjective form) might incorrectly imply something about functional programming principles, which could mislead beginners. The React team wants to avoid that little trap. It’s a bit like proper vocabulary or jargon specific to the React community – using the right term makes sure everyone understands each other without confusion.

The humor in the tweet also comes from the tone: “psst: in this house we say…” – it feels like a friendly whisper from the React team to its followers. It’s as if the React community is a family or a club with its own lingo. If you’re new to React, you might not have realized there’s even a distinction. But those who’ve been around a while have seen people correct each other on this exact point. It’s a community in-joke. The tweet’s timing and phrasing implies the React team is playfully throwing shade at the wrong term (“functional”) while reinforcing the correct one (“function component”).

This highlights something about Developer Experience (DX) too: consistent language in docs and code can make learning and collaborating easier. It might feel like a trivial detail, but consistent naming avoids mix-ups. Many frameworks and libraries have these little preferred terms. For example, in React we say props (short for properties) to describe data passed to components, and everyone learns that term. Here, they’re just nudging us to use the agreed term “function component” so that when you read official guides or discuss issues, everyone’s on the same page. And of course, it’s done with a wink and a smile – acknowledging that, yes, developers can get a tad obsessive about naming. After all, there’s a famous saying: “Naming things is one of the hardest problems in computer science.” This tweet turns that seriousness into a bit of tech humor. It’s React’s way of lightly saying: “We care about this little wording, and we know our developer community cares (and jokes) about it too.” If you’ve ever seen developers quibble over whether to call something a “bug” or an “issue”, or whether a file should be named UserDAO vs UserRepository, you’ll recognize the pattern. Here it’s just on a smaller, meme-worthy scale with a specific React twist.

Level 3: Function Over Functional

The official React Twitter account’s cheeky reminder — “psst: in this house we say 'function component', not 'functional'” — hits a nerve only seasoned frontend developers fully appreciate. It’s poking fun at a naming convention that has sparked countless code review nitpicks and style-guide debates in the React community. On the surface, it’s a single word difference. But in the world of Frontend Development, that tiny 'al' suffix carries surprising weight.

Why do senior React devs smirk at this tweet? Because they’ve lived through the naming holy wars. In React’s early days, we casually said “functional component” to mean a component written as a function instead of a class. It was an easy shorthand to contrast with the older class components. But over time, the React core team nudged everyone toward the term “function component”. Why so pedantic? Chalk it up to clarity and a bit of Developer Experience (DX) polish. The word functional brings along baggage from functional programming (FP) — a paradigm where functions are pure and side-effect-free. React’s function components aren’t necessarily pure; with Hooks like useState and useEffect, they can have state and side effects. Calling them “functional” started to feel like a misnomer, especially after Hooks let these once-stateless components become stateful. It’s as if the community collectively agreed: let’s drop the misleading suffix and stick to the basics.

This tweet reads like an inside joke between React veterans. The phrasing “in this house we say X, not Y” mimics a common meme format and implies a kind of tongue-in-cheek doctrine. The React core team is gently asserting their preferred terminology, and experienced devs find it hilarious because it echoes all those PR comments and docs changes they’ve seen:

• Code reviewer: “Great work on the component! Just a nit: we prefer calling it a function component rather than functional component for consistency with the docs.” 😅
• Team lead: “Our style guide flags ‘functional component’ — we follow official React nomenclature.”

Yes, this has even led to joke ESLint rules and elaborate bikeshedding. Bikeshedding, for the uninitiated, is when teams argue endlessly over trivial issues (like paint color… or naming). Seasoned devs have a scar or two from these battles. They know naming things is famously one of the hardest problems in programming (right up there with cache invalidation and off-by-one errors!). So, when React’s official account drops a playful “psst” about saying function instead of functional, it’s both a lighthearted grammar lesson and a reminder of how seriously our industry takes naming. It’s funny because it’s true: we obsess over terminology even while wrestling with complex framework mechanics. This tiny tweet encapsulates a shared experience — the collective sigh and chuckle of developers who’ve been down the rabbit hole of naming conventions, where a single word can spark a mini flame-war or a long Slack thread. In a fast-moving frontend framework ecosystem (where Framework Fatigue is real), it’s oddly comforting (and comical) to rally around something as small and enduring as a terminology preference. React’s tweet is essentially saying: “We’ve been through hooks, context, suspense, and countless new APIs together — we can at least get our naming straight, right?” 😉
