⏳ I spent mass amount of time studying RxJS operators. Not because the concepts are impossible — but because the right tools didn't exist. 🔍 A few timeline tools are out there, but they cover barely a handful of operators. The popular ones. The easy ones. What about the rest? What about comparing mergeMap vs concatMap side by side with the same input? I couldn't find a single tool on the internet that did that. 📖 Docs explain behavior in words. Marble diagrams are static. Stack Overflow assumes you already get timing. None of them let you experiment. 🛠️ So I built what I wished existed — and it's live right now for anyone to use. 🔗 RxJS Labx — a free, open-source interactive playground to learn RxJS operators visually. Here's what you get: ▶️ Live Visual Timelines — Watch values flow through operators in real time, not static images 📦 115 Operators — Not just the popular ones. Every operator across 9 categories, each with its own playground, description, and live syntax ⚡ Instant Experimentation — Change inputs, hit Run, see the output update instantly. No setup. No boilerplate. 🔀 23 Side-by-Side Comparisons — The feature that doesn't exist anywhere else. Run mergeMap vs concatMap vs switchMap vs exhaustMap against the same input and finally see exactly how they differ 🔧 Resizable Panels — Drag to resize. Toggle sections on/off. Focus on what matters to you ⚠️ Deprecated Operator Coverage — Full working playgrounds with clear guidance on modern replacements 📱 Works on Mobile & Desktop — Learn on the go or at your desk Whether you're a student just starting with reactive programming, a developer switching to Angular, or someone who's used RxJS for years but still second-guesses operator choices — this is for you. 💡 The whole idea is simple: If you can see it, you can understand it. I built this because I needed it. I'm sharing it because I think the RxJS community needs it too. 🌐 Try it live → https://lnkd.in/dUMQYSfZ ⭐ Star on GitHub → https://lnkd.in/dZBZdQdG Built with Angular & RxJS. Fully open source. Free forever. If this saves even one developer from the confusion I went through — worth it. 🏷️ Tag someone who's learning RxJS. They'll thank you later. 👇 #rxjs #angular #javascript #typescript #webdevelopment #opensource #frontend #reactiveprogramming #learning #angulardev #webdev #softwaredevelopment #coding #programming • Angular (Angular) • RxJS community
