Web Development

This Web Development collection is a strong starting point whether you’re learning your first tags or deepening an existing practice. MDN Web Docs and web.dev anchor the set with careful coverage of the web platform — HTML, CSS, JavaScript, browser APIs, accessibility, performance, and more — mixing references with practical guides, courses, and technical articles. W3Schools, Codecademy, and GeeksforGeeks add more hands-on learning paths, interactive practice, quizzes, coding challenges, projects, and broader programming topics, so you can move between quick lookups, structured lessons, and interview or competitive-programming prep without losing momentum.

There are also useful tools and platform-specific hubs for building beyond basic webpages. JSONPlaceholder is handy when you need a public REST API with sample JSON for prototyping, tutorials, or frontend testing. React Native and Flutter cover cross-platform app development from different angles, with documentation, tooling guidance, samples, and ecosystem resources for building mobile and other app experiences. Apple Developer rounds things out for anyone working in Apple’s ecosystem, bringing together documentation, downloads, sample code, design guidance, forums, videos, events, and App Store program information. And if you like sharpening your skills through play, CodinGame offers programming puzzles, AI bot battles, themed challenges, and competitive coding sessions.
