Why React's useState Doesn't Reflect Changes Immediately?



React's state management can be tricky, especially when you're new to the framework. One of the most common misconceptions is how the useState hook handles state updates. In this tutorial, we'll dive deep into why state changes don't reflect immediately and how to work around this asynchronous behavior.

Understanding Asynchronous State Updates

When you call setState in React, the update is not processed immediately. Instead, React batches multiple state updates for performance optimization. This means that when you log the state right after calling setState, you might not see the updated value right away.
