___________________ 🎙️ Speeding Up React Native Apps the "Old" C++ Way 🎙️ In this talk, we'll explore how the ""old-school"" power of C++ can breathe new life into modern React Native applications. When it comes to processor-heavy tasks like cryptography, image processing, or real-time data crunching, JavaScript alone can fall short. That's where native modules come in. We'll dive into how integrating C++ with React Native via the Native Modules and JSI (JavaScript Interface) can lead to dramatic performance improvements. You'll see how leveraging decades of C++ performance optimization can solve today's mobile bottlenecks—efficiently and effectively. Whether you're building secure messaging apps, crunching large datasets, or just curious about blending old and new tech, this session will show you how C++ still earns its stripes in the mobile world.
