*JavaScript Hoisting Tip* In JavaScript, variables and functions are hoisted to the top of their scope. before code execution. ✔ "var" is hoisted and initialized with **undefined** ✔ "let" and "const" are hoisted but stay in the **Temporal Dead Zone** until declared. # Best practice: Always declare variables at the top of your scope to avoid unexpected bugs. #JavaScript #WebDevelopment #Frontend #CodingTips

Simple JavaScript problem. Clean solution. Find unique characters in a string 👇 Most developers write extra logic for simple problems. The language already gives you tools. You just need to use them properly. How would you solve this WITHOUT using Set? #JavaScript #WebDevelopment #CodingTips #Frontend #Developers

React is killing complex logics day by day more better code optimization and better performance New React pattern (use() + async support): #ReactJS  #FrontendDevelopment  #WebPerformance #LearningInPublic  #JavaScript  #Consistency

❓ Ever wondered why JavaScript sorts numbers “wrong”? Try this: [1, 10, 2].sort() Output: [1, 10, 2] Wait… why not [1, 2, 10]? 🤯 🧠 The reason: By default, JavaScript’s .sort() converts numbers into strings and sorts alphabetically. So it compares: "1", "10", "2" And "10" comes before "2". Sneaky default behavior 👀 ✅ The fix: arr.sort((a, b) => a - b) Now JS knows it’s numeric sorting. Tiny detail. Big difference. Sometimes bugs aren’t errors — they’re misunderstood defaults 😌 #JavaScript #WebDevelopment #CodingJourney #Frontend #Developers

Things wish knew when I started frontend: -The browser is your best debugging tool. Learn DevTools deeply. - CSS isn't broken. You just don't understand the box model yet. - JavaScript fundamentals matter more than any framework. -Your first 10 projects will be ugly. Ship them anyway. Number 4 is the one most people skip. #Frontend #WebDevelopment #JavaScript #CSs #DevLife #SoftwareEngineering Serah ABIJO

POV: You install one “small” npm package. Your project: 😌 Your node_modules: 🔥🔥🔥 We don’t install dependencies in JavaScript… We adopt their entire family tree. And somehow we still say, “It’s lightweight.” #JavaScript #ReactJS #NodeJS #WebDevelopment #Frontend #ProgrammingHumor

The React Compiler removes the boilerplate that used to confuse our components. No more useMemo. No more useCallback. Just pure, readable JavaScript. The future of #React is all about developer velocity. #React #NextJS #WebDevelopment #Frontend #JavaScript

JavaScript Event Loop – Quick Example Understanding the Event Loop is important for writing efficient asynchronous JavaScript. Example: console.log("Start") const prom = new Promise((res) => res(true)) setTimeout(() => console.log("setTimeout"), 0) process.nextTick(() => console.log("nextTick")) queueMicrotask(() => console.log("microtask")) console.log(prom) Output order will be: Start Promise { true } nextTick microtask setTimeout Why? Because JavaScript processes tasks in this order: 1. Synchronous code 2. Microtasks (nextTick, Promises, queueMicrotask) 3. Macrotasks (setTimeout, setImmediate) Understanding this helps when debugging async issues in frontend apps. #javascript #webdevelopment #frontend #vuejs #eventloop
