Write real Arduino C++ and run it on a virtual Uno in a 3D maze. An in-browser compiler with avr-gcc-style errors, raycast sonar sensors, motor physics, PD wall-following and live telemetry.

Research comparing 3D built with pure HTML, CSS and JavaScript against libraries like Three.js and React Three Fiber, weighing effort, performance and what each approach can render.

A full-stack product built by a team of four: a React and TypeScript frontend with an Express, MongoDB and Firebase backend, taken from product idea to working site.

A browser game built with React: turn-based play, win and draw detection, and component state driving the board.

Practical steps for getting Amazon SES email into the inbox instead of spam: authenticate with DKIM, SPF and DMARC, keep lists clean and segmented, and keep bounce and complaint rates low to protect sender reputation.

A real problem from a microservice: duplicate rows in an email-stats table. It shows how to make upserts safe with column constraints and a partial unique index, so an email and thread pair stays unique only while the record is not archived.

Why TypeScript is worth the setup cost in a React app: typed props, state and events catch bugs before runtime and make a growing codebase easier to maintain. Walks through what TypeScript adds and how to set up a typed React project.

A hands-on setup for micro frontends: a React host app loads separately built remote apps through Vite’s module-federation plugin, so teams can build, deploy and scale features independently.

Why hooks replaced class components for most work, with a close look at useState and useEffect: how they give function components state and side effects and make logic easier to reuse.

Compares the two common ways to share state in React. Code examples show where the built-in Context API is enough and where Redux’s single store, actions and tooling pay off in larger apps.

Practical ways to keep a React app fast: tidy dependencies, one UI library, fewer wrappers, sized and cached images, production builds, code splitting, lazy-loaded routes, a CDN and fewer re-renders.

How React Router moves users between views of a single-page app without full page reloads: installing it, building a sample app with routes and links, and reading URL parameters.

Using LocalForage for offline-friendly storage in React: an async, localStorage-like API backed by IndexedDB that stores objects, not just strings, and falls back to localStorage when needed.

The two ways to write a React component side by side: how functional and class components differ in syntax, state, lifecycle and features, and when each one fits.
