Dynamic Imports in JavaScript Improve Page Load Time

React 19 / Next.js App Router introduces use() — a new way to handle async data. Before: useEffect + useState + boilerplate Now: use() + Suspense = clean & declarative #react #nextjs #javascript #frontend #webdevelopment

Frontend apps don’t break suddenly, they decay through small decisions. In this carousel, I share why React codebases become hard to maintain and what actually helped me fix them in real projects. If you’ve ever seen a file no one wants to touch, this will feel familiar. What was the first sign your codebase was getting messy? #ReactJS #FrontendDevelopment #JavaScript #SoftwareEngineering #WebDevelopment #FrontendArchitecture #DeveloperExperience

🚀 Using Jest for React Component Testing Jest is a popular JavaScript testing framework that integrates seamlessly with React. It provides features like mocking, snapshot testing, and code coverage reports, making it a powerful tool for testing React components. To use Jest, you'll typically write test cases in files with the `.test.js` or `.spec.js` extension. These test cases use Jest's `expect` function to make assertions about the component's behavior. Jest also provides built-in matchers like `toBe`, `toEqual`, and `toContain` to simplify the assertion process. Configuring Jest is usually straightforward with Create React App. Learn more on our website: https://techielearns.com #ReactJS #Frontend #WebDev #React #professional #career #development

⚛️React Journey: Performance Optimization React apps slow down from excessive re-renders, big bundles, and unoptimized lists. These 5 techniques can boost FPS by 60%+ and cut load times in half. Why Optimize? Re-renders: Every keystroke re-renders the whole tree. Bundle Size: 1MB JS = 3-5s load on mobile. Lists: 1000 items? Browser chokes without virtualization. Profile with React DevTools Profiler first, then apply. Most apps see 30-60% gains.

One of those tiny code patterns that still quietly lives in many mobile codebases in 2026. Yes, I am talking about the comma operator trick. Why though? Well, because It is concise and it works. Simple as that. While more developers today may prefer the more explicit version for better readability: onPress={() => {   router.push('/profile')   onClose() }} both do exactly the same thing, so it is just a matter of taste or DX at this point I guess. Quick reminder that what’s actually happening here is basically the comma operator (,) evaluates every expression from left to right and in this case, it is used on a React Native app to navigate to a new screen while closing a modal. Do you still write this pattern in your projects or has your style-guide officially banned the comma operator? #ReactNative #JavaScript #CleanCode #MobileDev #Frontend #TypeScript

Most React apps don’t have a useEffect problem… They have a thinking problem Before adding useEffect, ask yourself: Can this be derived instead?

Quick Next.js tip 👇 If you are using on-demand revalidation, there are two different levels you can invalidate. 🔹`revalidatePath` refreshes a specific page ✅ 🔹`revalidateTag` refreshes shared data used across pages ✅ Choosing the right one makes a big difference once your app grows. Here is how they compare in practice. 👇 Which one do you reach for more often?
