Learning React.js Functions for Cleaner Code

🚀 Learning React: Understanding Props Today, I learned an important concept in React called Props (Properties). Props allow us to pass data from one component to another, making our code more dynamic, reusable, and efficient. Instead of writing the same code again and again, we can create flexible components that adapt based on the data they receive. 🔑 Key Takeaways: Props are used to transfer data between components They make components reusable Props are read-only (cannot be modified inside the component) 📌 Example: We can pass values like names, images, or functions from a parent component to a child component using props. Learning props is a big step toward building real-world React applications 💻 #ReactJS #WebDevelopment #FrontendDevelopment #JavaScript #CodingJourney #LearnToCode #ReactLearning

"Hot take: Learning React before mastering JavaScript feels like a superpower until you hit a wall 🧱 🧱 React does such a great job of streamlining our workflow that it’s easy to forget how much 'magic' it’s doing under the hood. If you’re struggling with JS fundamentals now, don't sweat it—you're just finally meeting the engine that powers your favorite library!" Working with React is so easy if you follow JS way 👍🏻👍🏻 ❗❗ React looks very hard when you aren't able to tackle most of the problem which requires js fundamental. #React #Javascript #FrontendDevelopment #WebDevelopment

Mistake Post (useReducer) A mistake I made while learning React. I used 10+ useState hooks in a single component. The result? • confusing updates • hard-to-track logic • difficult debugging Everything looked fine at first, but as the component grew, the state management became chaotic. The solution I discovered later was useReducer. It centralizes all state updates into a single reducer function and uses actions to update the state. The component suddenly became much easier to understand. Lesson learned: useState for simple state useReducer for complex state logic HashTag: #reducer #useReducer #react #JavaScript

Learning React is exciting. But I’ve noticed many beginners make one mistake: They try to learn React while skipping HTML and CSS. The reality is simple: Browsers don’t understand React. Browsers understand only three things: 👉 HTML 👉 CSS 👉 JavaScript React is just a tool. Node is just an environment. The real foundation of frontend development is: 👉 JavaScript 👉 HTML 👉 CSS When fundamentals are weak: • Frameworks feel confusing • Simple bugs feel frustrating • Progress feels slow That’s why many beginners struggle — not because frameworks are hard, but because fundamentals are missing. Frameworks will change over time. But strong fundamentals stay with you forever. #webdevelopment #frontenddeveloper #reactjs #javascript #htmlcss #codingjourney #softwaredevelopment #learnincode #buildinpublic #careergrowth

⚛️ Learning React in 2026? Don’t Skip These Fundamentals React is everywhere, but many developers focus only on tutorials and syntax. The difference between a beginner and a strong React developer? Understanding how and why things work under the hood. 💡 Must-Know React Concepts: Components: Functional & Class JSX (JavaScript XML) Props vs State Hooks: useState, useEffect, useRef Virtual DOM & Reconciliation Conditional Rendering Lists & Keys Event Handling Controlled vs Uncontrolled Components React Router Interview Tips & Notes 🚀 Pro Tip: Don’t just memorize—practice building small projects while applying these concepts. That’s how mastery happens. 💬 Question for you: Which React concept did you struggle with the most when you started? #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #CodingInterviews #TechCareers

My React.js Learning Journey When I started with React, concepts like state management and component lifecycle felt overwhelming. But over time, I learned: - How to build reusable components - Managing global state using Redux & Recoil - Integrating REST APIs - Handling dynamic rendering - Writing cleaner, modular code The biggest lesson? Understanding fundamentals of JavaScript deeply makes React much easier. Still learning. Still improving. #ReactJS #JavaScript #WebDevelopment #LearningJourney #Redux #Recoil

💻 Building Forms in React with TypeScript I wanted to share a small learning experience from my recent training while working with React and TypeScript. Today I worked on building a form using React, and it turned out to be a really interesting hands-on exercise. A form might look simple at first, but once you start adding validation, managing state, and handling user feedback properly, you realize how many things are actually happening behind the scenes. While building the form, I used React hooks like useState and useEffect to manage form data and updates. I also implemented input validation using Regex so that fields like name, contact number, and duration follow the required format. Some things I practiced while building this: • Managing input fields with useState • Handling form submission and events • Showing error messages when fields are empty or invalid • Preventing form submission when validation fails • Displaying proper feedback after a successful update One thing I found interesting is how React makes form handling more structured compared to traditional JavaScript DOM manipulation, because the UI and state stay connected. At the same time, it also reminded me how important JavaScript fundamentals are, since frameworks like React are built on top of it. Still learning and exploring more every day. 🚀 #React #TypeScript #JavaScript #ReactHooks #FrontendDevelopment #LearningJourney

JavaScript is indeed a very wierd language. Maybe because it was developed in just 10 days to add dynamic behaviour to otherwise static HTML pages. The deeper you dive into JavaScript, the wierder it becomes. 1. Higher Order Functions -> Functions can be passed as arguments and returned from other functions. 2. Closures -> The inner function still remembers its neighbouring variables even after the outer function completes execution. 3. Callbacks -> A function can be passed as an argument to another function, to be executed later (usually after some async operation completes). 4. Callback Hell -> If multiple such callbacks are nested together, you are stuck in this 'Pyramid of Doom' 5. Promises -> An object which represents the current state of an asynchronous operation that can be returned from async functions to avoid the callback hell while chaining sequential async steps. 6. async / await -> More elegant way to make asynchronous code look and feel synchronous, but still make it non-blocking. And honestly we have not even started OOPS in JavaScript. The so called 'Prototypal Inheritance' and the binding of 'this' keyword which is the most confusing part of JS makes this language very difficult to master. But the good news is that you dont have to study everything. Instead you have to study just enough concepts to get the work done. For front end frameworks like React and Vue.js just the functional programming concepts mentioned earlier is sufficient. Take a look at this video where Keerti Purswani from Educosys explains these concepts in the most simplest of ways. It really helped me set my basics right. https://lnkd.in/gJWgMQf2 Here is the link to my GitHub repo where you can find code which I did while following the tutorial. https://lnkd.in/gzSacyg5 #ReactJS #VueJS #Angular #NextJS #JavaScript #JS

📚 Today’s Learning – React Strict Mode 1.It runs additional checks and warnings for unsafe lifecycle methods, unexpected side effects, and deprecated APIs. 2.One interesting behavior is that components may render twice in development to help detect side effects. 💡 Key takeaway: Strict Mode doesn’t affect production builds, but it helps catch bugs early during development and encourages writing safer, cleaner React code. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #CodingJourney #LearnInPublic

⚛️ Sharing My React.js Notes Just shared my React.js notes to help anyone who is starting or revising React. React can feel overwhelming at first, but once you understand components, props, state, and hooks, everything starts making sense. I created these notes to simplify the core concepts and make learning React easier for beginners and developers who want quick revision. 📘 These notes focus on: • Components & JSX • Props & State • React Hooks • Event Handling • Basic React Concepts Hope this helps developers who are on their React learning journey 🚀 📌 Save this post for revision 💬 Comment “REACT” if you want the notes 🔁 Share with someone learning React All credit goes to the original creator of the material. #React #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #Coding #Developers #TechLearning
