Day 72 / 365 👨💻 Continued learning React today. 🧠 Understood what React actually is 🔗 Learned what ReactDOM does ⚖️ Compared React vs ReactDOM 🧱 Looked at why they’re separate (native, PDF, etc.) ⚙️ Tried building a simple custom ReactDOM renderer 🚀 Learned about React 18 createRoot rendering ✨ Saw why JSX becomes useful #365DaysOfCode #React #JavaScript #Frontend

Today I learned about Lists & Keys in React. Lists allow us to render multiple items dynamically using methods like map(). For example: We can display a list of users, products, or tasks easily. Keys are used to uniquely identify each item in a list. This helps React efficiently update only the changed elements instead of re-rendering everything. Using unique keys improves performance and avoids bugs. Up Next: Forms in React 👀 React Series – Day 8 🚀 #ReactJS #LearningInPublic #WebDevelopment #FrontendDeveloper #JavaScript #100DaysOfCode

Controlled Components in React Today I learned about Controlled Components in React. A controlled component is a form element whose value is controlled by React state instead of the DOM. This means React manages the input values using state and updates them through event handlers. 📌 How It Works The input value is stored in state The input field uses that state as its value When the user types, an onChange event updates the state This way React fully controls the form data. Understanding controlled components helped me see how React manages form inputs efficiently.

📘What I learned about useEffect in React today One thing that confused me earlier was when useEffect actually runs. Here’s a simple breakdown: 👉 Runs after the component renders. 👉 Can be controlled using dependency array. 👉 Useful for API calls, subscriptions, side effects. 💡 Example use case: Fetching data when component loads. Key takeaway: 👉 Always understand dependencies, otherwise it may cause unnecessary re-renders. Still learning and improving every day 🚀 #reactjs #javascript #webdevelopment #learninginpublic

🚀 React developers often get confused between useState and useEffect. Here’s a simple way to understand it: 🔹 useState – Used to store and update component state. 🔹 useEffect – Used to handle side effects like API calls, timers, or DOM updates. Understanding these two hooks is essential for writing clean and efficient React applications. I created this simple visual to explain the difference 👇 What React topic should I explain next? #ReactJS #WebDevelopment #FrontendDevelopment #JavaScript #ReactHooks #useState #useEffect #Coding #SoftwareDeveloper #MERNStack #LearnToCode

Many beginners think querySelector() in JavaScript and useRef() in React do the same thing. But React uses a Virtual DOM, so direct DOM manipulation can break React’s flow. That’s why useRef() gives controlled access to the DOM while keeping React’s architecture intact.

💡3 Common Mistakes Beginners Make in React 1️⃣ Not understanding useEffect dependencies 2️⃣ Mutating state directly instead of using useState setter 3️⃣ Not breaking UI into reusable components Avoiding these can save a lot of debugging time 👆 I’m currently improving my React skills daily 🚀 #reactjs #javascript #webdevelopment #learninginpublic #frontenddeveloper

Recently put together a short guide on Zod for schema validation in React. If you’ve ever struggled with messy validation logic or unexpected runtime errors, Zod makes things a lot simpler and more structured. In this presentation, I covered: • What Zod is and why it’s useful • Basic and advanced validation examples • Handling errors with clear messages • How it integrates with React Hook Form It’s a small but practical overview that can really improve how you handle forms in React. ✨ #ReactJS #JavaScript #TypeScript #Zod #FrontendDevelopment #WebDevelopment #SoftwareDevelopment
