New TypeScript Devs Discovering the 'any' Type

Level 1: Unbuckled Seatbelt

Imagine someone in a car who just drapes the seatbelt over their shoulder without actually clicking it in. They then say, “Look, I have my seatbelt on – I’m safe!” Clearly, they missed the whole point: the seatbelt isn’t buckled, so it’s not protecting them at all. This meme is joking about a similar idea in programming. A new coder is using TypeScript (which is supposed to be a safety feature to catch mistakes), but they set everything to any – basically turning that safety off. They’re proudly thinking, “I’m using the new safety tool, so I must be safe, right?” But everyone else can see the truth, just like with the unbuckled seatbelt: it’s not actually doing anything. It’s funny and a bit silly because the person thinks they’re being extra safe, when in reality they aren’t safe at all.

Level 2: Any Means Anything

Let’s break down the joke in simpler terms. TypeScript is a programming language built on JavaScript that adds the idea of static typing. That means you can declare what type of data a variable should hold (for example, number, string, etc.), and the TypeScript compiler (the tool that checks your code and then converts it to JavaScript) will make sure you’re using those variables correctly. This gives you type safety – the compiler catches many mistakes (like mixing up types) before you even run your code. For instance, if you said a variable is a number and later try to treat it as a string, TypeScript will throw an error during compile time. This is great for code quality because it prevents a lot of bugs early on.

Now, what is any? In TypeScript, any is a special type that basically means “whatever – it can be anything.” If you give a variable the type any, you’re telling TypeScript not to enforce any checks on it. It’s like saying, “Don’t worry about what type this is; I’ll handle it.” This makes that variable work a lot like a normal JavaScript variable, which can change type freely without complaints. Here’s a quick comparison to illustrate the difference between using any and using a specific type in TypeScript:

// Using 'any': no compile-time type checking
let flexible: any = "Hello";
flexible = 42;                      // No error: 'flexible' can be a string, then a number... whatever!
console.log(flexible.toUpperCase()); // No error from TypeScript, but ⚠️ this will crash at runtime if flexible is not a string

// Using a specific type (string):
let greeting: string = "Hello";
greeting = 42;  // ❌ Compile error: Type 'number' is not assignable to type 'string'

In the first part, we declared flexible as any. TypeScript then allowed us to assign a string, then a number to it. It even let us call toUpperCase() on flexible without complaint. (Calling toUpperCase() makes sense if flexible were still a string, but here it’s actually the number 42 at runtime – something that would cause a crash. TypeScript didn’t warn us, because flexible was any and “anything goes”.) In the second part, we declared greeting as a string. When we tried to assign a number to greeting, TypeScript immediately gave an error. This is TypeScript catching a mistake – you said greeting should always be a string, and the compiler is enforcing that rule. This example shows how any basically turns off the rules, whereas a real type (like string) keeps you safe by preventing wrong assignments.

Now, back to the meme: The new TypeScript developer in the picture is using any everywhere, like our first example. The text “NEW TS DEVS” and the butterfly labeled “any” with the question “Is this TypeScript?” perfectly captures a common newbie misunderstanding. The dev sees that by using any, all those frustrating compiler errors disappear, and their code runs. They think, “Great, I’m writing in TypeScript now because it compiles!” But the joke is that, although the file says .ts, they aren’t getting the real benefits of TypeScript at all. It’s technically TypeScript, but with all the safety nets taken away.

For many beginners (especially those coming from a pure JavaScript background), strict type rules feel new and sometimes cumbersome. It’s tempting to use any as a quick fix whenever the compiler yells about a type mismatch. In the short term, this makes the error messages go away and the code compile. But in the long run, it can lead to the same problems JavaScript has – hidden bugs due to unexpected types. It’s a bit like turning off an alarm because the noise is annoying, even though the alarm was there to protect you. The meme highlights this learning-phase mistake in a funny way. New TypeScript devs ask “Is this TypeScript?” while holding up the any type, and experienced devs smile because the answer is: “Well, kind of... but not really!” The lesson for a junior developer is: using TypeScript effectively means actually specifying and respecting types. If you just make everything any, you’re back to square one (normal JavaScript) and missing out on the tool’s real power. Over time, as you learn, you start avoiding any unless absolutely necessary, and that’s when you’re truly “doing TypeScript right.” 😄

Level 3: Type Safety Mirage

Seasoned TypeScript developers often chuckle (or sigh) at this meme because it hits on a very real scenario. In the classic “Is this a pigeon?” anime scene, our eager newbie (labeled "NEW TS DEVS") is pointing at the any type and sincerely asking, “Is this TypeScript?” The humor comes from the irony: using any is essentially opting out of static typing entirely, making your code as loosely typed as plain JavaScript. It creates a type safety mirage – the code carries a .ts extension and passes the compiler, but it isn’t benefiting from TypeScript’s main perk: catching type errors at compile time.

Under the hood, any is a special top type in TypeScript’s type system. Think of it as a wildcard that says “I can be anything.” You can assign a string to it, then a number, or call any method on it – the TypeScript compiler won’t object. This is an intentional escape hatch for flexibility (for example, when migrating a large JavaScript codebase to TypeScript, any can fill in gaps where types are unknown). However, new devs often misuse it as a crutch: whenever the compiler complains “Type X is not assignable to Type Y,” the quick fix is to slap : any on that variable. Problem solved, right? Not really. They’ve basically told the compiler to ignore type mistakes, defeating the purpose of TypeScript in the first place.

Experienced engineers recognize this immediately as a common beginner mistake – a classic case of type safety confusion. The meme exaggerates that confusion: the newcomer genuinely believes using any everywhere means they're writing “proper” TypeScript. From a code quality standpoint, excessive any usage is often dubbed TypeScript in name only because it strips away the benefits of the language. It’s like painting over warning signs: the code compiles without errors, but you’ve lost all the safety warnings. If everything is typed as any, the compiler stops helping you catch bugs. A grumpy senior dev might quip, “If you’re going to use any for every variable, you might as well be writing plain JavaScript!” In other words, code full of any is basically JavaScript with extra steps – you run it through the TypeScript compiler, but you won’t get any of the usual guarantees.

This scenario is painfully relatable in the dev community – hence its popularity in developer humor circles. It pokes fun at the learning curve of TypeScript. Teams and mentors try to steer juniors away from this habit by enabling strict compiler settings (like noImplicitAny or the broader strict mode in tsconfig.json) which make it harder to accidentally use any. Newer TypeScript versions even introduced the unknown type as a safer alternative to any (you must check an unknown value’s type before using it, which keeps the safety intact). Seasoned devs know that mastering TypeScript means embracing its rich type system – using interfaces, union types, generics, etc. – rather than bypassing it. That’s why this meme strikes a chord: it’s a lighthearted reminder of the “awkward beginner phase” in learning TypeScript. We laugh because many of us have been that person asking “Is this TypeScript?” while unknowingly turning off the very feature that makes TypeScript so powerful. It’s funny, a tad cringe, but ultimately comforting – we all learn and grow past the any-everything stage!
