Hey! I've recently started my journey into frontend development, and I wanted to share my experience transitioning from plain JavaScript to TypeScript in React projects. As someone who's been learning React for the past few months, I've discovered why everyone keeps talking about TypeScript.
My First Steps with TypeScript
When I first started learning React, I was comfortable with JavaScript and honestly wondered why I should bother with TypeScript. Most job postings I saw required TypeScript experience, but I was a bit intimidated. Then I built my first React project with just JavaScript, and well... let's just say debugging became my full-time job. I spent hours tracking down simple prop type errors that could have been caught earlier.
That frustrating experience pushed me to give TypeScript a try. Setting up my first TypeScript project was pretty straightforward:
Here's a simple example of how I started using TypeScript in my components:
bash
npx create-react-app my-first-ts-app --template typescript interface
UserCardProps {
name: string;
age: number;
isActive: boolean;
}
const UserCard = ({ name, age, isActive }: UserCardProps) => {
return (
<div>
<h2>{name}</h2>
<p>Age: {age}</p>
<p>Status: {isActive ? "Active" : "Inactive"}</p>
</div>
);
};
The Learning Curve
I'll be honest - the learning curve was real. I remember staring at my screen for an hour trying to figure out why my map function wasn't working with a custom type. And don't even get me started on generics! But each small victory made me more confident.
Some challenges I faced:
Understanding the difference between type and interface
Figuring out how to type API responses
Working with event handlers in TypeScript
Dealing with null/undefined checks
What's Working for Me
The biggest game-changer has been the improved developer experience. Having my editor tell me exactly what props a component needs, instead of finding out through runtime errors, has saved me so much time. Plus, the autocomplete suggestions feel like having a coding buddy who remembers all the things I forget!
The Future of TypeScript
Even as a junior developer, I can see that TypeScript is no longer a luxury but becoming a necessity in the frontend world. Looking at job postings, almost every React position requires TypeScript experience. It's not a coincidence that major companies like Airbnb, Microsoft, and Google are using TypeScript in their projects.
Even React's official documentation now includes TypeScript examples, and popular frameworks like Next.js come with TypeScript by default. I'm glad I started learning TypeScript because it seems like it's only going to become more important in the future.
With the rise of AI tools, writing type-safe code seems to be gaining even more importance. The type safety that TypeScript provides is particularly valuable in large projects and team collaborations.
I'm still learning, and there's a lot I don't know yet, but I can already see why TypeScript is becoming so popular in the React community. If you're on the fence about trying TypeScript, I'd say go for it. Start small, embrace the error messages (they're actually helpful!), and don't worry about getting everything perfect right away.
Resources that helped me:
TypeScript's official documentation (though it can be overwhelming at first)
Matt Pocock's TypeScript tutorials on YouTube
React TypeScript Cheatsheet on GitHub

Let's learn together! Would love to hear about your experiences with TypeScript - especially if you're also just starting out! ๐
