React Context is a tool for managing global state without props drilling, allowing components to share data between each other without passing props down manually. It reduces code complexity and makes it easier to maintain.
XState is a library that simplifies complex state management in React applications by treating application state as a finite state machine (FSM). It provides a clear, well-defined structure for managing states and transitions, making code simpler, predictable, and easier to maintain.
React Profiler is a built-in tool that helps identify and optimize performance bottlenecks in React applications, providing valuable insights into rendering behavior to inform optimization decisions. It enables developers to make data-driven decisions about optimization by analyzing the app's rendering calls, timeline, and markers. By using React Profiler, developers can pinpoint areas where their app is slowing down and apply techniques like memoization, lazy loading, or minimizing DOM mutations to optimize performance.
