React State Updates Batched for Performance

useImperativeHandle is one of the most underrated React hooks. useImperativeHandle lets a parent trigger specific actions in a child component — focus, reset, open, close — without exposing internal logic. #ReactJS #ReactHooks #FrontendDevelopment #JavaScript #WebDevelopment #SoftwareEngineering #CleanCode #UIEngineering #FrontendEngineer

Today I learned about Lists & Keys in React. Lists allow us to render multiple items dynamically using methods like map(). For example: We can display a list of users, products, or tasks easily. Keys are used to uniquely identify each item in a list. This helps React efficiently update only the changed elements instead of re-rendering everything. Using unique keys improves performance and avoids bugs. Up Next: Forms in React 👀 React Series – Day 8 🚀 #ReactJS #LearningInPublic #WebDevelopment #FrontendDeveloper #JavaScript #100DaysOfCode

Unpopular opinion: Most React codebases are just jQuery with extra steps. 👀 Components that do 10 things. State scattered everywhere. useEffect doing God's work. Clean React is: → One component, one job → State that lives where it belongs → Effects that actually make sense The framework isn't the problem. The habits are. #React #WebDevelopment #Frontend #CleanCode #JavaScript

Built a Product Sorting Feature in React! I implemented dynamic sorting using useState and an array.sort() now products reorder instantly based on user selection. 🔹 Sort by Price (Low → High, High → Low) 🔹 Sort by Name (A → Z) 🔹 Used the spread operator to avoid mutating the original array This helped me understand how state + sorting works in real projects. 💻 Tech: React.js, JavaScript #ReactJS #JavaScript #FrontendDeveloper #WebDevelopment #CodingJourney

I just deleted 30 lines of code from a React component. no refactor. no library. just one hook in React 19. it's called use() — and it changes how you handle async data and context in your components. most devs haven't heard of it yet. swipe through ↓ broke it down simply what's the most boilerplate you've deleted in a single React upgrade? 👇 #react #react19 #javascript #webdev #frontend

While working on a full-stack project with Next.js, I sometimes needed to quickly check environment variables without modifying the code. Here’s a simple way to do it directly from the terminal (required 'dotenv' library): Check env value: node -e "require('dotenv').config(); console.log(process.env.DATABASE_URL)" It’s a small tip, but quite useful when you want to check env value. I’ll probably share a few more small things like this from my project along the way. #nextjs #nodejs #dotenv #webdevelopment #softwareengineering #buildinpublic #javascript #devtips #webdevUK
