The text explores the concept of batched updates in React, focusing on how the framework handles state updates differently depending on the context in which they occur. When updates are made within known methods like lifecycle methods or event handlers, React automatically batches them to minimize re-renders. However, updates within asynchronous callbacks, such as Promises or setTimeout, are processed synchronously, causing multiple re-renders. The article demonstrates how using the `ReactDOM.unstable_batchedUpdates()` function can force React to batch updates even in asynchronous scenarios, thereby optimizing performance by reducing unnecessary renders. Although this API is labeled "unstable," it is currently endorsed for production use by the React team, with expectations that future versions of React will inherently support this behavior by default. The text also suggests that developers should consider refactoring multiple state updates into a single call or combining state objects to adhere to best practices and reduce potential performance issues.
