    gear shifter, because it's easier to find than to aim for a 4cm wide area on a fully flat surface.

    React Performance Tip #12: Since modern CPUs are square, format your code to exact squares to make sure it fits on the CPU as efficiently as possible. This ensures that the CPU can directly execute the optimized format and will execute code much faster! 🤯

    Built with VisionCamera. All the drawing and blurring is happening with JavaScript code, and it runs in realtime. No post-processing. This is going to change the entire mobile camera game. Get ready.

    We'll launch react-native-filament this week - a blazingly fast physically based 3D rendering engine built with C++ for React Native! 🚀 As a teaser, here's a 47 line component to load a 3D model from the web, render it and rotate, pan and zoom into it using gesture handler! 🤯

    This is a React Native app running on my Mac, which uses my iPhone as a remote Camera over the air. 🤯 All made possible by react-native-vision-camera!

    .@lauridskern and I rebuilt Doodle Jump in React Native — the main game loop runs in a Reanimated useFrameCallback(), and everything renders using Skia. Runs pretty smooth! 🤩
