JavaScript Fundamentals: Closures, Promises, and Event Loop

Most beginners don’t fail because frontend is hard. They fail because they learn it the wrong way. If I started again today, I would avoid these 5 beginner mistakes completely. If you’re learning frontend right now, this will save you months of confusion.

If you understand JavaScript deeply, you can build almost anything. *Frontend. *Backend. *APIs. *Full systems. Most developers only reach the basics. They learn the syntax, but rarely grasp how things operate under the surface. JavaScript isn’t just a programming language. It’s the foundation of how users experience the web. From real-time updates to interactive interfaces, JavaScript makes applications feel alive. Concepts like asynchronous programming, event handling and DOM manipulation make JavaScript a tool for solving real problems, not just styling interactions. 1. Execution context. 2. Asynchronous behavior. 3. Event loop. That’s where the real power is. Don’t just learn JavaScript, understand it. #JavaScript #Developers #Tech #Programming #Growth

A strong online presence doesn’t happen by chance it starts with the right foundation. Every decision, from initial planning to final deployment, is made with clarity and purpose. This isn’t just about building a website. It’s about creating a system that performs under pressure, scales with growth, and delivers consistent results over time. Speed isn’t optional. Scalability isn’t an afterthought. And performance isn’t a bonus it’s the standard. If your digital presence is meant to grow, it should be built to handle it from day one. #WebDevelopment #FrontendDeveloper #SoftwareEngineering #NextJS #ReactJS #JavaScript #TypeScript #WebApps #Tech #Programming #DevelopersLife #Code #BuildInPublic #DigitalProducts #ScalableSystems #Performance #ModernWeb #UIEngineering #WebPerformance #FullStack #TechSolutions #Codexilo

Hi Devs, Clean code beats more code. Focus on quality, follow standards, and write with purpose. Great developers build maintainable solutions, not just lines of code. Consistency and clarity always win. 💫 #FrontendDeveloper #ReactJS #ReactDeveloper #JavaScript #WebDevelopment #Frontend #UIUX #WebDesign #Coding #Programming #SoftwareDeveloper #FullStackDeveloper #TechCommunity #HTML #CSS #TypeScript #NextJS #Redux

⚛️ React Components Explained In React, everything is built using components. There are two types: • Functional Components – simple, modern, and use Hooks • Class Components – older, more complex, and less used today 👉 Today, developers prefer Functional Components for clean and scalable code. Are you using functional components in your projects? #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #Coding

Closures used to confuse me a lot… until today 💡 Now I realize it's just about a function remembering its data. Simple idea, powerful use. If you're learning JavaScript, don’t skip this 🚀 💬 Do closures make sense to you now? #JavaScript #WebDevelopment #Frontend #CodingJourney #Developers

Create Custom Hooks in React 🚀 If you repeat logic across components, it's time to create a custom hook. Benefits: • Reusable logic • Cleaner components • Easy maintenance • Better architecture Custom hooks make your code more scalable and professional. This is one of my favorite React patterns. What custom hooks do you use in your projects? #reactjs #customhooks #frontenddeveloper #mernstack #javascript #reactdeveloper #webdevelopment #coding #developers #reactpatterns

🚀 I built a VS Code Extension! I recently created DevStruct — a VS Code extension that generates clean, production-ready project structures in seconds. 💡 Problem: Setting up folders for every new project is repetitive and time-consuming. ⚡ Solution: With DevStruct, you can instantly generate structured setups for: • React (Frontend) • Node.js (Backend) • Full Stack apps Just run a command and you're ready to start building. 🎥 Demo included in the extension page. 🔗 Try it here: https://lnkd.in/gHxYEPZM I’d really appreciate your feedback — what should I improve or add next? #vscode #webdevelopment #javascript #typescript #opensource #developers

Just published a new blog on Array Flattening in JavaScript 🚀 If you've ever worked with nested arrays and wondered how to convert them into a single-level array efficiently, this one's for you. I’ve covered different approaches—from built-in methods to custom logic—with clear examples. 🔗 Read here: https://lnkd.in/dVgZ_SUT Would love to hear your thoughts and how you usually handle nested arrays in your projects! #JavaScript #WebDevelopment #Coding #Frontend #Developers #100DaysOfCode

Why your website is slow (and how pros fix it) Most developers think their site is slow because of the server. But in reality? It’s usually because of simple mistakes: Unoptimized images No lazy loading Too much unnecessary JavaScript Professional developers focus on performance first: Audit using Lighthouse Optimize images properly Reduce JS bundle size The truth is simple: Your site is not slow… your decisions are. What’s the biggest performance mistake you’ve made before? #WebDevelopment #FrontendDeveloper #Performance #NextJS #SoftwareEngineering #Coding #WebDev #TechTips #DeveloperLife
