Mirrow: A DSL for Dynamic SVG Creation and Animation — Instead of treating SVGs as static graphics, Mirrow reimagines them as interactive, code-defined visuals. It introduces a domain-specific language (DSL) that lets you generate and animate SVGs programmatically, making them flexible, reusable, and expressive. Visit the playground to experiment with Mirrow syntax and bring your own SVG animations to life in real time.

React Compiler v1.0 — The React team has officially declared the compiler stable and ready for production use. It automatically applies memoization optimizations based on static code analysis, reducing unnecessary re-renders and improving performance without manual tweaks. You can still rely on useMemo and useCallback for fine-grained control when needed, but many optimizations are now handled seamlessly by the compiler itself.
