🧠 “I don’t write TypeScript — I design context.” — Alper AKBAƞ

📅 Why This Article?

My frontend journey began with Vue 3, but I recently decided to switch gears and explore React. Along the way, I gave TypeScript a more serious look.

I had used it briefly before, but this time I told myself:

“Let’s write more TypeScript and see what kind of difference it makes.”


I noticed something fascinating — my AI-powered editor, Cursor, went into overdrive!

As I began writing even just a function signature:

* More accurate code completions

* Context-aware suggestions

* Early error detection and dependency insights all kicked in impressively.


The reason behind this? ✅ TypeScript.


📚 JavaScript vs TypeScript: A Simple but Striking Example

JavaScript:

function greetUser(user) {
  return `Hello, ${user.name}!`;
}

greetUser({ isim: "Alper" }); *// → "Hello, undefined!"*

TypeScript:

type User = {
  name: string;
};

function greetUser(user: User): string {
  return `Hello, ${user.name}!`;
}

greetUser({ isim: "Alper" }); *// ❌ Property 'name' is missing
While JavaScript silently lets the bug slide, TypeScript — and your LLM — raise the red flag instantly. That’s the power of explicit types.


✹ Why TypeScript is LLM-Friendly

TypeScript:

* Requires you to annotate types for functions, parameters, and objects.

* Acts like a manifest for LLMs (ChatGPT, Claude, Gemini, etc.).

* Helps the model understand your intent before you even finish writing the code.


In short: using TypeScript isn’t just about pleasing the compiler — you’re also speaking clearly to your AI assistant.


đŸ€– The Cleanest Way to Communicate with LLMs: Static Typing

Let’s be blunt:

If you don’t give your LLM types, you’ll end up with bugs. And those bugs multiply in large-scale projects.

Static typing is the backbone of LLM-powered code completion:

  • It boosts the model’s accuracy.

  • Helps predict test cases and outputs.

  • Improves the readability of shared code in team environments.


⚖ TypeScript = Fewer Bugs, More Context

TypeScript helps you:

  • Communicate the intent and boundaries of your code.

  • Reduce side effects.

  • Clarify function inputs and outputs.


Without these, LLM-assisted development can feel like blind autocomplete.

đŸ•č Advice for Aspiring Modern Developers

If you want to be an AI-assisted developer, you should:

✅ Learn TypeScript

✅ Master type systems

✅ Express context through code

✅ Become a developer who can “talk” to your editor and model


And always remember:


“I don’t write TypeScript — I design context.”

📝 Final Thoughts


In the LLM era, we don’t just need correct code — we need clearly expressed code.

TypeScript helps make your code understandable to both humans and machines.


To every new frontend developer out there:

âžĄïž Start using TypeScript early. You’ll thank yourself later.
