JavaScript & React: Assignment vs Reassignment vs Mutation

⚛️ Day 4 of Learning React.js Today I learned about Props in React.js. I understood that props (short for properties) are used to pass data from one component to another. This makes components more dynamic and reusable instead of hardcoding values. What I learned today: What are props in React How to pass data from parent to child component Using props inside functional components Making components reusable with different data Now I can create components that display different content based on the data passed to them. It’s starting to feel more structured and powerful compared to plain JavaScript. Step by step learning and improving every day 🚀 #ReactJS #FrontendDevelopment #JavaScript #WebDeveloper #LearningJourney #StudentDeveloper #Consistency

📚 React Learning — useEffect Today I revised the useEffect hook in React and understood how it helps handle side effects like API calls, timers, and event listeners. Also practiced how the dependency array controls when the effect runs and why the cleanup function is important to avoid memory leaks.

⚛️ Day 3 of Learning React.js Today I learned about Components in React.js. I understood that components are the building blocks of a React application. Instead of writing everything in one file, we can divide the UI into small, reusable pieces called components. What I learned today: What are components in React Functional components How components help in reusable UI Basic structure of a React component This concept makes development more organized and scalable compared to plain HTML and JavaScript. Still learning step by step. Excited to explore JSX and props next 🚀 #ReactJS #FrontendDevelopment #JavaScript #WebDeveloper #LearningJourney #StudentDeveloper #Consistency

I was literally stuck while trying to understand the Context API in React. I explored many tutorials, but the concept still wasn’t completely clear. Finally, I came across the React playlist by @VinodBahadurThapa on the YouTube channel Thapa Technical, and it completely changed my understanding. The explanation of Context API was simple, practical, and beginner-friendly. Now, it feels smooth and much more logical to implement in real projects. Grateful for such quality content that genuinely helps developers grow. 🙌 If you're struggling with React concepts, I highly recommend checking out the playlist. #ReactJS #ContextAPI #FrontendDevelopment #JavaScript #LearningJourney #WebDevelopment

⚛️ Day 9 of Learning React.js Today I learned about Functions in JavaScript and how they are used in React. I understood that a function is a block of code that performs a specific task and can be reused whenever needed. Functions help make the code cleaner, more organized, and easier to manage. What I learned today: What is a function Why functions are important How to create and call a function How functions are used inside React components How event handling works using functions Now I can see how functions control logic and interactions inside a React application.

React gives us powerful optimization tools… But many devs use them randomly. Here’s the simple rule: 🟠 useEffect → for side effects (API calls, subscriptions, DOM work) 🔵 useMemo → to memoize computed values 🟢 useCallback → to memoize functions If you use useEffect for calculations… you’re misusing it. If you pass new functions every render… you cause re-renders. The goal is NOT to use all 3 hooks. The goal is to use the right hook for the right job. Which one confused you the most when learning React? 👇 #ReactJS #FrontendDeveloper #WebDevelopment #JavaScript #CodingTips #ReactHooks #MERNStack #SoftwareDevelopment

The biggest mistake beginners make in JavaScript? Watching tutorials without building anything. You don’t learn JavaScript by consuming content. You learn it by building small, imperfect projects. A calculator. A to-do app. A simple weather dashboard. These “small” projects teach you more about logic, DOM manipulation, and debugging than 20 hours of passive learning. If you're starting out, here’s a curated list of beginner-friendly projects that actually build confidence: 🔗 https://lnkd.in/g-RCUC9B Developers — what was the first project that made you feel like a real programmer? #JavaScript #WebDevelopment #LearnToCode #Codersera #BeginnerDevelopers #ProgrammingJourney
