Use dynamic routes like `path: '/user/:id'` to capture params with `useParams()`. Combine with `<Outlet />` in parent layouts to render nested child components dynamically. #ReactJS #WebDev

Wrap your app in `<BrowserRouter>`. Define paths with `<Route path="/" element={<Home />} />`. Use `<Link to="/about">` instead of `<a>` tags to prevent full page reloads. #ReactJS #WebDev

Share state between sibling components by lifting it to their closest common ancestor. Pass the state down as props, and update it using callback functions. #ReactJS #WebDev

For complex state logic in React, swap `useState` for `useReducer`. It centralizes state transitions in one reducer, making updates predictable and easier to test. #ReactJS #WebDev

Stop prop drilling. Use React's `useContext` to share global state like themes or auth data directly with deeply nested components. Clean, maintainable, and built-in. #ReactJS #MERN

Every render in React recreates inline functions, changing their reference. Wrap them in `useCallback` to preserve identity and prevent child components from re-rendering unnecessarily. #ReactJS #WebDev

Optimize React performance with `useMemo`. It caches the result of an expensive calculation between renders, only recalculating when its dependency array changes. #ReactJS #WebDev

Use `@Media (max-width: 768px)` in your React CSS to build responsive layouts. Always design mobile-first: style the mobile view first, then scale up using media queries. #CSS #ReactJS

Git merge conflicts occur when two branches edit the same file line. Fix them by choosing `Accept Current` or `Incoming` change, then stage and commit. #Git #WebDev

Keep your MERN main branch stable. Create feature branches with `git checkout -b feature-name`, push, and open a Pull Request (PR) for peer review before merging. #Git #MERN

async/await makes asynchronous code look synchronous. Use try/catch for clean error handling instead of .catch() chains. Always prepend await to promises inside an async function. #JavaScript #WebDev

JS Promises handle async operations without callback hell. They exist in 3 states: pending, fulfilled, or rejected. Chain them with `.then()` or resolve them cleanly using `async/await`. #JavaScript #MERN

Use `array.reduce((acc, cur) => acc + cur, 0)` to transform an array into a single value. The accumulator (`acc`) persists across iterations. Essential for state derivation in MERN apps. #JavaScript #MERN

Use `map()` to transform every element in an array. Use `filter()` to select elements based on a condition. Both return a new array, keeping your original data immutable. #JavaScript #MERN

MongoDB is a NoSQL database storing data in flexible, JSON-like documents. Unlike SQL tables, schemas can vary per document, making it perfect for rapid iteration in MERN apps. #MongoDB #MERN

Map HTTP methods to CRUD in Express: GET (Read), POST (Create), PUT (Update), DELETE (Delete). Pair them with correct status codes like `201` for created and `400` for client errors. #MERN #WebDev

In Express, use `req.params` for required path variables like `/users/:id`. Use `req.query` for optional filtering like `/users?role=admin`. Keep routes clean and RESTful. #ExpressJS #WebDev

Express routing connects HTTP methods to handlers. Use `app.get('/', (req, res) => res.send('OK'))` for routes, and `app.listen(3000)` to start your server and listen for incoming requests. #ExpressJS #MERN

Use Node's `path` module for cross-platform file paths. `path.join()` safely merges segments, while `path.resolve()` creates absolute paths. Never hardcode `/` or `\` separators. #NodeJS #WebDev

Use `fs.promises` in Node.js for clean, async/await file operations instead of callback hell. Avoid blocking the event loop with synchronous methods like `fs.readFileSync`. #NodeJS #Backend
