TypeScript: Overrated or Essential in 2025?

TypeScript has exploded in popularity over the past few years — from sidekick to JavaScript, to being the default for most modern projects.

But not everyone is on board.

Some developers swear by it. Others feel it’s overhyped and adds unnecessary complexity.

So let’s ask the big question: Is TypeScript truly essential, or is it just overrated hype?

✅ Why People Say TypeScript is Essential

1. Catches Bugs Before They Happen

TypeScript adds static type checking — so you catch errors before you run your code.

Fewer runtime errors = faster debugging = better dev experience

2. Great DX in Large Codebases

TS shines in large apps where teams need to:

• Understand unfamiliar code

• Refactor safely

• Avoid silly mistakes

3. Better Autocomplete & IDE Support

Once you try VSCode with TypeScript types, it’s hard to go back. The autocomplete is accurate, intelligent, and just feels ✨good✨.

4. Improves Collaboration

When multiple devs are working on the same repo, TS acts like a contract:

“This function accepts this, returns that. Don’t break it.”

❌ Why Some Say It’s Overrated

1. Steep Learning Curve for Beginners

If you're just starting out, types, interfaces, generics, and weird error messages can feel overwhelming.

You spend more time fighting the compiler than writing logic.

2. Slows Down Rapid Prototyping

Building a quick MVP or side project? TS can feel like too much ceremony — especially if you're iterating fast.

3. You’re Already Using JS + JSDoc

Some devs argue that tools like JSDoc, ESLint, and modern JS are enough for “most” projects.

4. False Sense of Security

TypeScript makes you feel safe — but it won’t stop logic bugs. It’ll just ensure your bad logic has the right types 😅

🧠 So... Which Is It?

👉 It depends.

If you’re building:

• A large-scale app

• With multiple contributors

• That needs to be maintainable long-term

TypeScript is not just helpful — it’s almost essential.

But if you're:

• A solo dev

• Building fast prototypes

• Or just learning the ropes

Plain JavaScript is still totally valid — and can even be the better choice for speed and simplicity.

🔚 Final Thoughts

TypeScript is not perfect, and it’s definitely not always necessary. But it’s also not just hype — it solves real problems, especially in larger, long-term projects.

So no, it’s not overrated. But it is overused in places where it’s not needed.

Learn it, understand when to use it — and don’t be afraid to go plain JS when it makes sense.
