Evolving React Architecture from Context to Service Layer Today, I took a step toward senior-level React architecture by refactoring my state management logic. Instead of letting a "God Context" handle everything, I introduced a Service Layer for data persistence. By abstracting localStorage logic into a dedicated storage service, I’ve achieved: 1- Decoupled UI & Data: My components no longer care how data is stored. 2- Easier Scaling: Switching from LocalStorage to a real API now only requires touching one file. 3- Clean Code: My Context files are leaner and easier to maintain. Senior-level development isn't just about making things work—it’s about making things scale. #ReactJS #WebDevelopment #SoftwareArchitecture #CleanCode #JavaScript

🚀Day 101 of Cohort2.0 Today's class was about More on Instagram clone project with Ankur Prajapati at Sheryians Coding School In This session, we were introduced to 4 layer frontend architecture: 1). UI layer ⬇️ 2). Hooks ⬇️ 3). State layer ⬇️ 4). API layer i learned how each layer works and how to implement this architecture to make the code more manageable and scalable. i learned about different methods and functions to implement this architecture which helps in writing a clean code. #responsiveness #responsivedesig #css #scss #html #Cohort2 #webdevelopment #Javascript #react #DOM #frontend

I built a free practice section for frontend interview prep and it's live now. Over the past few weeks, I've been curating and organizing frontend interview questions into a structured, topic-wise Q&A format. The questions cover areas like:  • Currying & Closures  • Promises & Async patterns  • DOM manipulation  • Observable & Reactive programming  • …and more Most of the questions are sourced from BFE.dev and GreatFrontEnd two excellent platforms for frontend practice. I've organized them by topic with detailed solutions so you can use this as a quick-reference guide or a structured study plan. Whether you're preparing for your next frontend interview or just want to sharpen your JavaScript fundamentals, I hope this helps. Check it out here: https://lnkd.in/d27Dg6e8 If you find it useful, feel free to share it with someone who's preparing. And if you have feedback or want me to cover a specific topic, drop a comment! #FrontendDevelopment #JavaScript #InterviewPrep #WebDevelopment #CodingInterview #React #OpenSource

Understanding Node.js Architecture (Behind the Scenes of JavaScript Runtime) When I first started learning Node.js, one question confused me a lot: If JavaScript runs on a single thread, how can Node.js handle thousands of requests at the same time? The answer lies in the powerful architecture of Node.js, which combines the V8 JavaScript Engine, libuv, the Event Loop, and a Thread Pool to efficiently manage asynchronous operations.

Revisiting core JavaScript concepts with an interview-first approach (Frontend focus). Today: Promises & Async/Await — beyond just syntax. Key learnings: • fetch() returns a Promise, not actual data • Response is just a wrapper → data comes after .json() • .json() itself is asynchronous and returns a Promise • Missing return in .then() breaks the chain • Async/Await improves readability but follows the same Promise flow Applied these concepts by building a mini project: → Fetched GitHub user data using API → Dynamically rendered user cards (image + username + profile link) on the frontend Focused on strengthening fundamentals through practical implementation. #javascript #frontenddevelopment #webdevelopment #softwareengineering #interviewprep GeeksforGeeks Rohit Negi CoderArmy

This isn’t just an optimization — it’s a shift towards smarter frontend architecture.

A lot of frontend complexity is not actually a UI problem. It’s a data modeling problem. The moment your UI starts feeling messy or too conditional, there’s a good chance the real issue is happening before rendering even starts. It’s also about building a system where: Raw data → normalized model → predictable UI That shift changes everything. The more I work on frontend systems , the more I believe this: Frontend is not just presentation. It’s architecture. #FrontendDevelopment #WebDevelopment #SoftwareArchitecture #ReactJS #NextJS #TypeScript #JavaScript #CleanCode #FrontendEngineer #UIDevelopment #Programming #Developer #SoftwareEngineering #CodeQuality #SystemDesign

Writing a JavaScript Framework: Project Structuring Simplified   When building a JavaScript framework, structuring your project is everything. A well-designed architecture ensures scalability, maintainability, and performance.   This visual (inspired by RisingStack Engineering) highlights how different layers interact within a framework: 🔹 Middlewares – Handle core functionalities like routing, rendering, and data interpolation 🔹 Helpers – Tools like compiler and observer that power reactivity and optimization 🔹 Symbols & Components – The building blocks that connect logic with UI 🔹 Your App – The central piece that ties everything together seamlessly   💡 The takeaway? A strong separation of concerns and modular design is what makes frameworks robust and developer-friendly. If you’re exploring how frameworks work under the hood, this is a great starting point to understand the bigger picture.   ✨ Build smarter. Structure better.   #JavaScript #WebDevelopment #Frontend #Frameworks #SystemDesign #SoftwareArchitecture #FullStack #Developers #Coding #TechLearning
