𝗠𝘆 𝗙𝗶𝗿𝗦𝘁 𝗥𝗲𝗮𝗰𝘁 𝗣𝗿𝗼𝗷𝗲𝗰𝘁 Hi, I'm Ayra. I practiced HTML, CSS, and JavaScript. Then I challenged myself: I built a React project without tutorials. I chose Frontend Mentor's Digital Bank Landing Page Challenge. I rebuilt it using React. Here's what I learned: - React is component-based. You break your UI into small pieces. - React uses JSX. You write HTML-like syntax directly inside JavaScript. - React uses virtual DOM. It updates only what has changed. I started with the Header component. I stored navigation links in an array and rendered them dynamically: const links = ["Home", "About", "Contact", "Blog", "Careers"]; <ul className="nav__links" aria-label="navigation links"> {links.map(link => ( <li key={link}> <a href="#">{link}</a> </li> ))} </ul> This made my code cleaner and easier to maintain. I handled the toggle using state: import { useState } from "react"; function Header() { const [isOpen, setIsOpen] = useState(false); return ( <button className={`toggle ${isOpen ? "toggle--open" : ""}`} aria-label="menu toggle" aria-expanded={isOpen} onClick={() => setIsOpen(!isOpen)} > <span></span> <span></span> <span></span> </button> ); } Now I update the state and React handles the rest. I split my Header component into MobileMenu and Backdrop. Both depend on the same isOpen state. I passed it down as props: <MobileMenu links={links} isOpen={isOpen} /> <Backdrop isOpen={isOpen} onClose={() => setIsOpen(false)} /> You can check out my GitHub repo: https://lnkd.in/g7AbHRCh Source: https://lnkd.in/gMS2j_z3

Most people break promises. JavaScript doesn’t. 💙 Let’s talk about one of the most important concepts in JS — Promises — explained simply. A Promise is your code saying: “Trust me… I’ll return something. Maybe not now. But soon.” Every Promise has only 3 states: 🟡 Pending – Still working on it… 🟢 Fulfilled – Success! Here’s your result. 🔴 Rejected – Something went wrong. Think of it like ordering pizza 🍕 Pending → It’s in the oven Fulfilled → Delivered successfully Rejected → “Sorry, we ran out of cheese.” Here’s a simple example: const getPizza = new Promise((resolve, reject) => { const delivered = true; if (delivered) { resolve("🍕 Pizza arrived!"); } else { reject("❌ No pizza today."); } }); getPizza .then(result => console.log(result)) .catch(error => console.log(error)); .then() → Handles success .catch() → Handles errors .finally() → Because closure matters 😉 Good developers handle errors. Great developers handle promises. Now tell me 👇 Are you team .then() or team async/await? #JavaScript #WebDevelopment #Coding #SoftwareEngineering #Developers #AsyncProgramming #PromiseDay

𝐒𝐭𝐨𝐩 𝐦𝐞𝐦𝐨𝐫𝐢𝐳𝐢𝐧𝐠 𝐑𝐞𝐚𝐜𝐭 𝐬𝐲𝐧𝐭𝐚𝐱. 𝐒𝐭𝐚𝐫𝐭 𝐫𝐞𝐚𝐝𝐢𝐧𝐠 𝐜𝐨𝐝𝐞. When I started learning React, I believed progress meant remembering syntax, hooks, and patterns by heart. I tried to memorize how things worked instead of understanding why they worked. That approach didn’t last long. The moment I began building real projects, I realized something important: React is not about how much you remember. It’s about how well you understand structure, flow, and intent I made mistakes early on. I copied code without fully reading it. I fixed bugs without understanding their cause. Sometimes the app worked, but I didn’t know why it worked. That’s when I changed how I learn. Instead of jumping between tutorials, I slowed down. I started reading code line by line. I explored components written by others. I asked myself simple questions: What is this state doing? Why is this effect here? How does this data move through the component? This shift changed everything. Reading code helped me recognize patterns. It taught me how experienced developers think. It showed me that clean logic matters more than clever syntax. React became less confusing once I stopped treating it like something to memorize and started treating it like something to understand. Now, when something breaks, I don’t rush to rewrite it. I read the code. I trace the flow. I let the logic explain itself. There’s still a lot to learn. There will be more mistakes ahead. But now I know how to approach them — calmly, thoughtfully, and with curiosity. 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐜𝐨𝐝𝐞 𝐢𝐬 𝐚 𝐬𝐤𝐢𝐥𝐥.

JavaScript imports: Old vs Modern — what actually changed? If you started learning JavaScript a few years ago, you probably used require(). Today, most projects use import. At first glance, it looks like just a syntax change. In reality, the difference is much deeper. Here’s what changed. 1. Syntax and structure Old (CommonJS): const fs = require('fs'); module.exports = function greet() {  console.log("Hello"); }; Modern (ES Modules): import fs from 'fs'; export function greet() {  console.log("Hello"); } 2. When modules are loaded - CommonJS loads modules at runtime. - That means require() is executed when the code runs. - ES Modules are statically analyzed before execution. - The structure of imports and exports is known in advance. - This enables better tooling and optimization. 3. Synchronous vs asynchronous behavior CommonJS is synchronous by default. This works well in Node.js but doesn’t fit browsers perfectly. ES Modules are designed with asynchronous loading in mind and work natively in browsers. 4. Dynamic imports With CommonJS, you can require conditionally: if (condition) {  const lib = require('./lib'); } With modern JavaScript, you use dynamic import: if (condition) {  const lib = await import('./lib.js'); } 5. Performance and tree-shaking Because ES Modules are statically analyzable, bundlers can remove unused code (tree-shaking). With CommonJS, this is much harder. Why this matters ES Modules are now the standard for modern JavaScript — in browsers and in Node.js. They improve performance, tooling, and maintainability. CommonJS isn’t “wrong” — it’s just older. But for new projects, ES Modules are the better long-term choice. #JavaScript #ESModules #CommonJS #NodeJS #WebDevelopment #FrontendDevelopment #BackendDevelopment #SoftwareEngineering #Programming #Coding #WebDev #JSDeveloper #Tech #CleanCode

If your phone is using JavaScript, it says: 👉 “𝑂𝑘𝑎𝑦, 𝑠𝑎𝑣𝑒𝑑.” Everything looks fine until you actually try to call your friend 📵. Now imagine your phone is using TypeScript. This time, the moment you try to save “abcxyz” as a phone number, the system stops you and says: ❌ "𝐸𝑟𝑟𝑜𝑟! 𝐴 𝑝ℎ𝑜𝑛𝑒 𝑛𝑢𝑚𝑏𝑒𝑟 𝑚𝑢𝑠𝑡 𝑐𝑜𝑛𝑡𝑎𝑖𝑛 𝑜𝑛𝑙𝑦 𝑑𝑖𝑔𝑖𝑡𝑠." Now you can fix the mistake before saving the contact. 💡 That’s the core difference between JavaScript and TypeScript. ⭕ JavaScript → lets mistakes slip through and fails at runtime ⭕ TypeScript → catches mistakes early, while you’re writing code 🤔 𝐖𝐡𝐲 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫𝐬 𝐚𝐫𝐞 𝐬𝐰𝐢𝐭𝐜𝐡𝐢𝐧𝐠 𝐭𝐨 𝐓𝐲𝐩𝐞𝐒𝐜𝐫𝐢𝐩𝐭: ✅ Fewer runtime bugs ✅ ✅ Better editor autocomplete 🖊️ ✅ Easier teamwork 🤝 ✅ Self-documenting code 📚 👉 TypeScript is not replacing JavaScript — it’s a superset, adding a safety net so your apps run smoother. 💡 Whether you’re building a large front-end app, backend server, or enterprise system, TypeScript helps you avoid silly mistakes before they become big problems. 📖 Read the full medium article: 👉 https://lnkd.in/g-KiDGey #TypeScript #JavaScript #Programming #WebDevelopment #SoftwareEngineering

🚀 30 Days — 30 React Mistakes Beginners Make 📅 Day 1/30 ❌ Mistake: Mutating State Directly (No Re-render Happens) I changed the value… But UI didn’t update 😐 Code 👇 const user = { name: "Smeet" } user.name = "Rahul" setUser(user) I thought React was broken. 💡 What Actually Happened? React checks object references, not deep values. Since we mutated the same object, React saw: “Same reference? No need to re-render.” ✅ Correct Way setUser({ ...user, name: "Rahul" }) Now React sees a new object reference → triggers re-render. 🎯 Lesson Never mutate state directly. Always create a new object or array. Immutability = Predictable UI. #30DaysOfCode #ReactJS #JavaScript #FrontendDeveloper #WebDevelopment #CodingMistakes #ReactTips #LearnInPublic #100DaysOfCode #Developers
