Learn TypeScript | Code & Run vs Vraur

Learn TypeScript and write JavaScript that scales — types, generics and real project patterns. Bite-sized lessons with a code runner on your phone and an AI mentor that gives you instant, clear answers. Made for JavaScript developers levelling up, and for beginners aiming at frontend or Node.js jobs. WHY LEARN TYPESCRIPT? • TypeScript is the default for serious JavaScript work — React, Angular, Node and most modern codebases expect it • Typed code means fewer runtime bugs and much better tooling: autocomplete that actually knows your code • It's one of the most-requested skills in frontend and full-stack job listings • If you know JavaScript, you're closer than you think — TypeScript builds on what you already know WHAT YOU'LL LEARN • TypeScript fundamentals — types, variables, functions and control flow • The type system in depth — unions, narrowing and discriminated unions • Generics — write flexible code that stays type-safe • Type inference, utility types and everyday patterns • Using TypeScript with React components and Node.js backends • Strict compiler options, tooling and production-ready workflows EVERYTHING YOU NEED TO LEARN TYPESCRIPT • AI Mentor — confused by a generic constraint or a compiler complaint? Ask anything and get a clear answer in seconds • 100+ bite-sized lessons (5–10 minutes each) — short but genuinely deep • Real code editor — write and run code right on your phone • Quizzes and coding challenges after every topic to lock in what you learn • Weekly Code Challenge — compete with learners around the world • Certificate of completion — pass the final exam and prove your skills • Streaks, progress tracking and smart reminders to keep you consistent • Learn on the go — lessons load fast and keep working on flaky connections • App available in 22 languages WHO IT'S FOR • JavaScript developers who keep seeing TypeScript in job posts and codebases • React and Node developers who want end-to-end type safety • Beginners who'd rather learn the modern standard from day one • Anyone prepping for frontend or full-stack interviews MIGRATE WITH CONFIDENCE Already have a JavaScript project?

Vraur is an innovative AI-based way to learn English through active practice in context — an approach research suggests can help you remember vocabulary more effectively. One of the biggest challenges in learning English is not just memorizing new words, but practicing them actively enough to start using them in real life. Vraur is designed to help solve that problem. Instead of passively studying fixed vocabulary lists, you can save useful words and phrases you find in real life — in films, conversations, reading, work, or everyday situations — and practice them in context, so you not only understand them, but also learn how to use them yourself and, as a result, start using them actively in your own speech. How Vraur works: 1. Find a word or phrase you want to learn 2. Save it in Vraur 3. Choose a topic and difficulty 4. Practice by translating AI-generated sentences from your language into English 5. Get instant feedback to improve your vocabulary, grammar, and sound more natural in English. Why Vraur? – Learn useful words in context Save words and phrases that matter to you and practice them in real sentences, not in isolation. Research suggests that active practice in context can help vocabulary stay in memory longer. – Improve vocabulary and grammar together Instant AI feedback helps you understand mistakes, improve your grammar, and sound more natural in English. – Keep your vocabulary fresh Track when words were added and when you last practiced them. – Built for learners beyond the beginner stage If simple vocabulary apps already feel too easy, Vraur is designed for you. It helps you keep growing with more natural phrases, useful topics, and the right level of challenge. Vraur is designed for learners who want to build stronger vocabulary, practice actively, and sound more natural in English. Supported languages: Spanish, French, German, Italian, Portuguese (Brazil), Portuguese (Portugal), Dutch, Swedish, Danish, Norwegian, Polish, Czech, Russian, Ukrainian, Turkish, Romanian, Greek, Arabic (MSA), Indonesian, Vietnamese, Chinese (Simplified), Chinese (Traditional), Japanese, and Korean.
