React.memo for Component Optimization

🚨 “Build Failed” — and the reason was Suspense in Next.js That moment when everything works fine in development… But the build suddenly breaks. Yeah, I hit that. While working on a Next.js project, I ran into a Suspense-related error during build — and honestly, it forced me to go deeper than just “making things work.” Here’s what I realized 👇 ⚡ Suspense isn’t just a loader It’s a core part of how React handles async rendering now. ⚡ Next.js makes it even more powerful (and tricky) With Server & Client Components, you can’t just use Suspense anywhere blindly. 💥 My mistake? • Missing proper fallback • Not understanding where Suspense actually belongs • Mixing client/server logic without thinking And boom — build failed. 💡 The shift in mindset: Frontend is no longer just about UI… It’s about understanding rendering behavior. After fixing it, one thing became clear: 👉 If you’re using Next.js and ignoring Suspense, you’re missing a big piece of modern React. Still learning. Still breaking things.

🚀 Creating a Context with React.createContext To use the Context API, you first need to create a context object using `React.createContext()`. This function returns a Provider and a Consumer. The Provider component allows consuming components to subscribe to context changes. The Consumer component is used to read the context value. It's common to initialize the context with a default value that can be overridden by the Provider higher up in the component tree. #ReactJS #Frontend #WebDev #React #professional #career #development

React developers should know performance optimization. React.memo helps improve performance by preventing unnecessary re-renders. It works using a shallow comparison of props. If props stay the same → component skips re-render. When to use it: - Heavy or complex UI components - Components inside frequently re-rendering parents - Props that remain stable (same reference) How to get the best results: - useMemo → for objects and arrays - useCallback → for functions - Keep props clean and predictable React.memo works best when combined with good component design. #ReactJS #Frontend #Performance #WebDevelopment #React19 #FrontendEngineering #AsyncProgramming #CleanCode #DeveloperExperience #ReactNative

Can a framework have its own framework? Because must people call React a framework and Next.js a React framework and my brain is tired 😭 Let me settle this once and for all. React is a library. Not a framework. It gives you tools to build UI. That's it. You decide everything else. Next.js is the framework. Built on top of React. It gives you structure. Routing. Server side rendering. File based pages. Everything React doesn't give you out of the box. Think of it this way React is the engine. Next.js is the car. You can have an engine without a car. But the car needs the engine to move. Now the real question Which one are you more comfortable with and why? 👇🏾 Personally I am more comfortable with Next.js because i like structure. React alone gives me too much freedom and i end up scattered 🥲🥲 Drop your answer below. Let's argue. 👇🏾 #React #NextJS #Frontend #WebDevelopment #WomenInTech #AfricanInTech

💡 One thing I learned as a Frontend Developer Performance matters more than design. Optimizing components and reducing load time can completely change user experience. Tech I use: React.js + Tailwind CSS Still learning every day 🚀 #Frontend #ReactJS #Learning

𝗜 𝘀𝗵𝗶𝗽𝗽𝗲𝗱 𝗮 𝗡𝗲𝘅𝘁.𝗷𝘀 𝗽𝗿𝗼𝗱𝘂𝗰𝘁 𝗶𝗻 𝟭 𝗺𝗼𝗻𝘁𝗵. Not a side project. A real product. With real users waiting.🏁 Here's the backstory: At SoftConstruct, we needed a new product fast. The timeline was aggressive - 1 month from zero to deployment. I had solid React experience but had never used Next.js in production before.🤷 So I learned it on the job. While building. While shipping. Sounds chaotic? It was. But it also worked. Here's what made it possible: 1️⃣ 𝗥𝗲𝗮𝗰𝘁 𝗳𝘂𝗻𝗱𝗮𝗺𝗲𝗻𝘁𝗮𝗹𝘀 𝘁𝗿𝗮𝗻𝘀𝗳𝗲𝗿. If you really know React - hooks, state, component thinking - Next.js is not a new world. It's React with opinions. That foundation saved me weeks. 2️⃣ 𝗜 𝗱𝗶𝗱𝗻'𝘁 𝘁𝗿𝘆 𝘁𝗼 𝘂𝘀𝗲 𝗲𝘃𝗲𝗿𝘆 𝗡𝗲𝘅𝘁.𝗷𝘀 𝗳𝗲𝗮𝘁𝘂𝗿𝗲. No ISR. No complex middleware. I used what the project needed: SSR where it mattered, static where it didn't, and a simple file-based routing structure. Done. 3️⃣ 𝗗𝗼𝗰𝘀 𝗼𝘃𝗲𝗿 𝘁𝘂𝘁𝗼𝗿𝗶𝗮𝗹𝘀. I skipped the 4-hour YouTube courses. Next.js docs are genuinely good. When you're under pressure, go to the source. 4️⃣ 𝗜 𝘀𝗵𝗶𝗽𝗽𝗲𝗱 𝘂𝗴𝗹𝘆 𝗳𝗶𝗿𝘀𝘁, 𝘁𝗵𝗲𝗻 𝗶𝗺𝗽𝗿𝗼𝘃𝗲𝗱. The first deploy wasn't beautiful. But it was live. And that's when real feedback started flowing. Would I do things differently now? Absolutely. I'd set up better error boundaries from day one. I'd plan the data-fetching strategy before writing the first component. And I'd push back on at least one "nice-to-have" feature that cost me 3 sleepless nights.🥱🌙 But here's the thing - you don't learn these lessons from tutorials. You learn them from shipping under pressure. If you're a React dev thinking about Next.js - don't overthink it. Build something real. The gaps in your knowledge will reveal themselves fast, and that's exactly what you want. What was your first experience with Next.js like? Smooth or chaotic? #react #nextjs #frontend #webdevelopment #javascript #shipping

Day [18] of learning Code for Change Did a quick revision of React before diving into my Next.js project, and it was honestly worth it. Went back to basics like useState and useEffect, just to refresh how state updates, re-renders, and side effects actually work. Also revised concepts like props, component structure, lifting state up, and handling data flow between components. These are things we use all the time, but a small revision makes everything much clearer and easier to apply. Now starting with Next.js feels more confident and less confusing. Sometimes a simple revision is all you need before building something bigger. #ReactJS #NextJS #Revision #WebDevelopment #Frontend

🚀 Using Fragments with Keys (React Development) When rendering multiple elements within a list item, you might use React Fragments (`<> `) to avoid adding unnecessary DOM nodes. However, if you need to assign a key to the list item, you should use the explicit `` syntax. This allows you to provide a key for the entire fragment, enabling React to efficiently track changes. #ReactJS #Frontend #WebDev #React #professional #career #development

🚀 Day 3 – Props in React Props (short for properties) are used to pass data from one component to another in React. 🔹 Props are passed from parent to child components 🔹 They are read-only (cannot be modified) 🔹 Help in making components reusable and dynamic Example use: Passing data like name, price, or title to display different content in components. Props play an important role in building structured and maintainable React applications. #ReactJS #Props #Frontend #WebDevelopment #Learning
