Why I Switched to TypeScript
After years of writing plain JavaScript, I finally made the switch to TypeScript — and I'm never going back.
The Problem
JavaScript is flexible, but that flexibility becomes a liability as projects grow. I spent more time tracking down undefined is not a function errors than actually building features.
The Fix
TypeScript catches these mistakes at compile time:
function greet(name: string): string {
return `Hello, ${name}!`;
}
greet(42); // Error: Argument of type 'number' is not assignable to 'string'
The type system feels like a second pair of eyes on your code. If you're on the fence — try it on one file. You'll get it.
