I just created a simple number guessing game in JavaScript! 🕹️ It uses the `prompt-sync` module for user input, generates a random number between 1 and 50, and lets players guess the number with up to 5 attempts. The game provides feedback on each guess, telling players if they are too high or too low, and announces if they've won or lost. A fun way to practice loops, conditionals, and user input.

Meta has introduced React Compiler. Now is react is more optimized. Explained in the video. #developer #javascript #React #fullstack #webdeveloper #software #frontend

The TypeScript compiler, a complex yet intriguing, serves as an ideal introduction to get yourself into compiler design. The following image illustrates high level components of the "tsc" and how each connect to produce JavaScript code The drawing made using https://excalidraw.com/ TSC source code: https://lnkd.in/dMBsha99

WTF is #React Compiler? The core idea of React is that you define your UI as a function of the current state. This means that React re-renders whenever your app’s state changes, but it also means that React can re-render too much, degrading performance. You can prevent this with a magic combination of useMemo, React.memo, and useCallback. Unfortunately, you’re not a magician and manual memoization still has downsides: It makes your code less concise, less clear, and less composable, especially as your team/codebase scales. It requires you to imperatively tell React how to process your code, thus killing some of React’s declarative magic. There’s always that person on your team who is convinced in order to make React fast you need to memoize everything. This, turns out, makes React slower. This is where React Compiler comes in. It’s a low-level compiler that understands the rules of React and JavaScript, and can use that knowledge to automatically memoize your components for you. No more useMemo, useCallback, or awkward conversations with Mr. Memoize Everything. - Adrian 🟣 B.

#React Goodbye, UseMemo, UseCallback, and React.Memo 💪 React added a compiler in the React 19 release which would take care of all the necessary re-renders during state changes, which means React developer will not need to wrap their code inside useMemo or usecallback to prevent extra re-renders. 🎉 *React 19 new features* ✅ React Compiler ✅ Use Hook ✅ Form actions along with hooks useFormStatus, useFormState ✅ useOptimistic hook

For performance in react, we can think of react compiler.

I just made a calculator with JavaScript! I used two different approaches. The if/else if statement and the switch statement! https://lnkd.in/eebWxZHy

Next.js 15 RC is out 🎉 📌 Highlights - ▪️React 19 + React Compiler support ▪️ fetch` and Route Handlers no longer cached by default ▪️ Incrementally adopt Partial Prerendering ▪️ New `create-next-app` design ▪️ next/after (Experimental) 📌 Full Link: https://lnkd.in/gnJEDwdF
