+
+Jotai takes an atomic approach to global React state management.
+
+Build state by combining atoms and renders are automatically optimized based on atom dependency. This solves the extra re-render issue of React context, eliminates the need for memoization, and provides a similar developer experience to signals while maintaining a declarative programming model.
+
+It scales from a simple useState replacement to an enterprise TypeScript application with complex requirements. Plus there are plenty of utilities and extensions to help you along the way!

+MobX is a powerful and intuitive state management library that enhances application scalability and simplicity through its use of functional reactive programming. The core philosophy of MobX is rooted in straightforwardness and efficiency. Developers can write minimalistic, boilerplate-free code that clearly expresses their intentions. For instance, updating a record field is as simple as performing a standard JavaScript assignment, with MobX automatically detecting changes and propagating them throughout the application. This eliminates the need for specialized tools in asynchronous data processes.
