🚀 Day 1 of My 100 Days of Code — Setting Up React & Understanding the Fundamentals

Today was a solid learning day. I delved deeper into React.js, starting with how to properly set up the React development environment. I explored the traditional setup as well as installing React using Vite, which I found incredibly fast. Vite’s lightning-quick dev server and instant hot-reload made the whole experience smoother and more enjoyable.

I also learned how different dependencies work in a React project, and how they help us write React code more efficiently.

Some of the core concepts I covered today include:

✅ Components

I learned how React uses components as the building blocks of every application. I also practiced nesting multiple components inside a parent component, which helped me understand how React structures UI.

✅ Class-Based vs Functional Components

I explored both class components and functional components. Even though functional components with hooks are more common today, it was great understanding how class components work behind the scenes.

✅ Rendering Lists

I learned how to render lists dynamically in React using .map(). This was exciting because I finally got to see how data flows into the UI efficiently.

🔥 My Coding Journey Continues

I just started a 100 Days of Code challenge, and I'll be dropping updates on what I’m learning and building along the way.

Stay tuned for more updates — the journey is only beginning! 💪🚀
