Custom Hooks are one of those React features that can significantly enhance your codebase. If you find yourself duplicating the same useEffect, state, or API logic across components, it's a clear indication that you should create a custom hook. In just three simple steps, you can: • Extract reusable logic • Keep components clean • Improve readability and maintainability This approach scales effectively for real-world applications and simplifies testing and reasoning about your code. Pro tip: If your component is doing too much, it’s likely time for a hook. Save this for later and share it with someone learning React. #ReactJS #FrontendDevelopment #JavaScript #WebDev #ReactHooks #CleanCode #DevCommunity 

Here is something new for react developers... I kept seeing the same pattern: useState works, useEffect works, but the mental model is missing. So I built #HooksHub a simple place for developers who are learning React and want to understand hooks properly, not just memorize syntax. It’s still evolving, but the goal is clear: explain hooks the way developers actually think.

99% of React beginners make this mistake. I was one of them. 😬 ━━━━━━━━━━━━━━━━ ❌ WRONG const [arr, setArr] = useState([]); arr.push(1); setArr(arr); ✅ RIGHT setArr([...arr, 1]); ━━━━━━━━━━━━━━━━ Why? React doesn't look INSIDE your array. It just checks—is this the same object? You mutated it. Same object. React shrugs. No re-render. 🤷 Always give React something NEW. Spread it. Slice it. Map it. Just don't mutate it. #React #JavaScript #Frontend #LearnToCode #ReactJS

DAY 20 OF POSTING REACT CONTENT ⚛️ WHAT DOES await REALLY DO? 🤔 await tells JavaScript: 👉 “Wait here until the Promise finishes.” It pauses the function until the result is ready. Example: async function getData() { const data = await fetchData(); console.log(data); } The code waits for fetchData() before moving to the next line. Cleaner than .then() Easier to read Same result #ReactJS #JavaScript #AsyncAwait #Promises #FrontendDevelopment #LearnInPublic #WebDevelopment #CodingJourney

🚨 A small TypeScript mistake I still see in React projects Many developers type their state setters as - (val: number) => void. It looks correct - but it silently breaks a core React feature. React state setters don't just accept a value - they also accept a function. This is essential when your next state depends on the previous one. If you type the setter wrong, functional updates won't typecheck. You've locked yourself out of a feature React gives you for free - and opened the door to subtle bugs. Typing setters correctly means: React's full API stays intact, refactors are safer across your codebase, and state bugs from stale closures become much harder to introduce. It's one line of types. But in a large codebase, it's the difference between code that works and code that works until it doesn't. If you use TypeScript with React, don't throw this away. #TypeScript #React #JavaScript #Frontend #CodingTips

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

💡 𝗧𝗶𝗽 𝗼𝗳 𝘁𝗵𝗲 𝗗𝗮𝘆 — 𝗥𝗲𝗮𝗰𝘁 𝗗𝗶𝗱 𝘆𝗼𝘂 𝗸𝗻𝗼𝘄? In React, 𝘀𝘁𝗮𝘁𝗲 𝘂𝗽𝗱𝗮𝘁𝗲𝘀 𝗶𝗻𝘀𝗶𝗱𝗲 𝗲𝘃𝗲𝗻𝘁 𝗵𝗮𝗻𝗱𝗹𝗲𝗿𝘀 𝗮𝗿𝗲 𝗯𝗮𝘁𝗰𝗵𝗲𝗱, meaning multiple "setState" calls may result in a 𝘀𝗶𝗻𝗴𝗹𝗲 𝗿𝗲-𝗿𝗲𝗻𝗱𝗲𝗿. Why it matters: - Improves performance automatically - Explains why consecutive state updates don’t always update immediately - Encourages writing state updates that depend on previous state using the functional form Understanding batching helps you write more predictable React code. #React #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #SoftwareEngineering #CodingTips #PerformanceOptimization #FullstackDeveloper

💡 Before React. Before Node. Before fancy frameworks. There is HTML, CSS, and JavaScript. And honestly? Most bugs I’ve seen in projects come from weak fundamentals — not advanced concepts. Here’s what strong basics actually mean: 🔹 HTML Understanding semantic tags, accessibility, proper structure. 🔹 CSS Knowing flexbox, positioning, box model, responsiveness — not just copying styles. 🔹 JavaScript Understanding closures, async/await, event loop, array methods — not just syntax. Frameworks change. Fundamentals don’t. The stronger your basics, the easier React, Node, or any tech becomes. Every time I improve my JS fundamentals, my React code improves automatically. #WebDevelopment #JavaScript #FrontendDeveloper #ReactJS #FullStackDeveloper #SheryiansCodingSchool
