React State vs Props: Understanding the Difference

While learning React, I recently explored what happens behind the scenes when the UI updates the concept of Reconciliation and the Diffing Algorithm. When a component’s state or props change, React does not immediately update the real DOM. Instead, it creates a new Virtual DOM tree and compares it with the previous one. This comparison process is called Diffing. React checks what actually changed between the two trees and then updates only those specific parts in the real DOM instead of re-rendering everything. This process of efficiently updating the UI is known as Reconciliation. For example, if only a text value changes inside a <p> tag, React updates just that node rather than rebuilding the entire DOM structure. This makes React applications fast and efficient. A couple of interesting things React assumes to make this process quicker: • Elements with different types create different trees • Keys help React track items in lists efficiently Understanding how React updates the DOM internally really helped me see why things like keys and component structure matter for performance. #React #JavaScript #WebDevelopment #FrontendDevelopment #ReactJS #Programming #LearningInPublic

🚀 Get ready to supercharge your coding game! Functional programming is the secret sauce 💡 that can elevate your JavaScript skills to new heights! Ever heard people rave about it but not sure why? It's not just a fad—it's a powerhouse tool. Imagine writing code that’s clean, bug-resistant, and easy to test. That's the magic of functional programming. Think about functions like you do pizza slices: everyone takes their piece without taking the whole pie. Yum! Functional programming's core concepts—pure functions, immutability, and higher-order functions—can make your code predictable and efficient. It's not just for the algorithm wizards; even practical web apps benefit hugely! Would you give this a spin in your next project? 🤔 Let’s get the conversation started!

React Hooks Explained (Simple Way) React Hooks changed how developers build modern React applications. They allow functional components to manage state, lifecycle behavior, and side effects without using class components. Some of the most commonly used hooks include: • useState – manage component state • useEffect – handle side effects like API calls • useContext – share global data between components • useRef – access DOM elements directly • useMemo / useCallback – improve performance Hooks make React code simpler, cleaner, and easier to maintain. Understanding hooks is essential for building modern React applications.

🚀 Understanding the React Component Lifecycle with Hooks When I first started learning React, one thing confused me a lot: When exactly do hooks run? Sometimes my useEffect ran twice. Sometimes state updates caused unexpected re-renders. And debugging it felt like chasing a ghost in the code. 😅 After spending time digging into it, I realized something simple: React components basically go through three main phases. 1️⃣ Mounting – The component is created This is when the component first appears on the screen. During this phase: useState initializes state useContext reads context useEffect([]) runs once after the first render 2️⃣ Updating – The component re-renders This happens whenever something changes. For example: State changes Props change Context changes React re-renders the component and then runs: useEffect([dependency]) only if the dependency changed. 3️⃣ Unmounting – The component is removed When a component disappears from the UI. This is where cleanup functions become important. Example: Remove event listeners Cancel API requests Clear intervals That’s why useEffect can return a cleanup function. 💡 One small insight that helped me: Think of React components like a life cycle: Born → Update → Die Once this mental model clicks, hooks become much easier to understand. I made this visual guide to simplify the concept 👇 💬 Curious to know: When learning React, which hook confused you the most? useEffect useState useContext Something else?

Understanding State and Props in React (Simple Explanation) If you are learning React, two concepts you must understand early are state and props. Props: Props are used to pass data from a parent component to a child component. They are read-only, which means the child cannot modify them. Example: A parent sends a user name to a child component. The child just displays it. State: State is used to store data inside a component. Unlike props, state can change over time. Example: A counter that increases when you click a button uses state. Key Difference: Props are external and immutable. State is internal and mutable. In simple words: Props = Data coming from outside State = Data managed inside the component Understanding this difference helps in building better and scalable React applications. #ReactJS #FrontendDevelopment #SolGuruz #WebDevelopment #JavaScript #Programming #SoftwareEngineering

State is the data that changes over time in your component. It makes your UI dynamic, interactive, and powerful. 👉 Without state → Static UI 👉 With state → Interactive App 📌 Example: Button clicks Form inputs Toggles Counters API Data ⚡ In React, when state changes → UI updates automatically. That’s the magic of Declarative UI. 🎯 Want to master React from basics to advanced?

In the world of web development, it’s tempting to jump straight into flashy frameworks like React or Next.js. But lately, I’ve realized that a house is only as strong as its foundation. I’m currently diving deep into JavaScript Fundamentals, and it’s been a game-changer. Re-learning the "why" behind things like Scope and Hoisting, Closures, Asynchronous patterns and so on. Mastering the fundamentals isn't a step backward; it’s the fastest way to move forward. If you understand the core of the language, the frameworks become easy to learn. Are you a "fundamentals first" developer, or do you prefer learning on the fly?

Most developers struggle with NestJS not because it’s complex… but because the core concepts are explained in a way that feels complicated. So I tried a different approach. I created a visual explanation of NestJS fundamentals as if a 5-year-old is learning them. Because once you simplify the four core pieces, the framework suddenly makes sense: 🪄 Decorators → Magic labels that tell NestJS what something does 🧹 Pipes → Clean and transform incoming data 🧰 Services → The place where the real work happens 🎮 Controllers → The traffic manager handling requests and responses When you understand how these pieces work together, NestJS stops feeling like a “new framework” and starts feeling like a well-organized system for building backend applications. I paired this explanation with simple code examples so beginners can connect the concept with real implementation. Sometimes the best way to learn complex systems is to explain them in the simplest possible way. If this kind of visual + simplified explanation helps you understand backend concepts: 👉 Like so more developers see it 👉 Share it with someone learning NestJS 👉 Comment the next concept you want explained this way #nestjs #nodejs #backenddevelopment #typescript #softwaredevelopment #webdevelopment #programming #developers #coding

⚛️ One concept that confused me a lot while learning React was: Props vs State At first they both felt similar. But a simple way to understand it is: 🔹 Props → Data passed from parent component 🔹 State → Data managed inside the component Example mindset: Props = Inputs State = Internal memory Props are read-only. State can change over time. Once I understood this difference, React components started making much more sense. Building UI is really about managing data flow properly. React just gives us a structured way to do it. #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #FullStackDeveloper Ankur Prajapati MOHD ALI ANSARI Sheryians Coding School

Here are 5 mistakes I made as a React developer 👇 And what they taught me: Overusing global state → Everything in Redux → Fix: Keep state where it belongs Ignoring performance early → Fixed later with difficulty → Fix: Think performance from start Writing large components → Hard to maintain → Fix: Break into smaller units Blindly trusting libraries → Used without understanding → Fix: Learn fundamentals first Not focusing on debugging → Took longer to fix issues → Fix: Build debugging skills These mistakes cost time. But they built experience. Today, I write code differently because of them. Growth in engineering is not about avoiding mistakes. It’s about: 👉 Learning fast 👉 Improving continuously What’s one mistake that made you better? #ReactJS #Learning #SoftwareEngineering #Frontend #Programming
