The React pattern that eliminated 80% of my useEffect calls Most useEffect calls are just bad data derivation. Here is the derived state pattern that cleaned up years of accumulated complexity in my React components.

React Query changed how I think about state — and I have not used Redux since The server state vs client state distinction that React Query makes explicit replaced my need for Redux entirely. Here is the mental model shift. Full breakdown (7 min read) → https://lnkd.in/gcUhHrV2 #ReactJS #Frontend #JavaScript #TypeScript #WebDev #UIEngineering

I once fixed a performance issue… Didn’t change logic. Didn’t add caching. Just replaced a loop with Promise.all() Speed went 📈 Sometimes the problem isn’t scale… it’s how you write async code. #SoftwareEngineering #NodeJS #JavaScript #Performance #DevTips

#JavaScript flexibility extends to both the client_side and server_side, allowing #developers to create complete web applications. Here’s how it functions in each environment: #Client_Side: Involves controlling the browser and its #DOM (Document Object Model). Handles user events like clicks and form inputs. Common libraries include #AngularJS, #ReactJS, and #VueJS. #Server_Side: Involves interacting with #databases, manipulating files, and generating responses. #Node.js and frameworks like #Express.js are widely used for server-side #JavaScript, enabling #full_stack_development. #Learn_JavaScript

🚀 JavaScript Tip: Always use === instead of == In JavaScript, == performs type coercion, which can lead to unexpected results. 0 == false // true 😬 0 === false // false ✅ 👉 == compares only value 👉 === compares value + type 💡 Using === helps you write predictable and bug-free code. Small change. Big impact. #JavaScript #WebDevelopment #CodingTips #Frontend #Backend #FullStackDeveloper #MERN #Developers

🚀 React + .NET = A Powerful Full-Stack Combination 💻 Modern web applications demand speed, scalability, and clean architecture. Pairing React on the frontend with .NET on the backend creates a powerful stack for building high-performance applications. #FullStack #React #DotNet #WebDevelopment #ReactJS #DotNet #Programming #CodingLife #JavaScript #CSharp #BackendDevelopment #FrontendDevelopment
