📄️ Incorrect State Update
This example illustrates a common mistake made by React beginners when updating state.
📄️ React Hooks Conditionally
This example highlights an important rule in React: hooks cannot be used conditionally.
📄️ Updating Object State
This example demonstrates how to properly update an object state in React.
📄️ Managing Form State
This example addresses how to manage the state of multiple form fields efficiently in React.
📄️ Deriving State
This example demonstrates the best practice of deriving information directly from existing state or props in React, rather than creating additional state variables for derived values.
📄️ Understanding Re-Renders
This example highlights the difference between using primitive and non-primitive values in React state management and how it affects re-rendering. When you use a primitive value (like 0), React performs a strict equality check (===), and if the value hasn't changed, it avoids unnecessary re-renders.
📄️ Handling Initial State
This example demonstrates proper initialization of state when dealing with asynchronous data fetching in React.
📄️ Handling Initial State
This example demonstrates proper initialization of state when dealing with asynchronous data fetching in React.
📄️ Cleaning Up Resources
This example demonstrates the significance of managing resources and cleaning up events in React components.
📄️ Server and Client Components
In Next.js, it's important to distinguish between server and client components because they operate in different environments with distinct limitations
📄️ Understanding Stale Closure
This example demonstrates the concept of a stale closure in React, which occurs when a function inside a useEffect hook refers to outdated state or props.
📄️ Handling Fetch Requests
This example demonstrates the correct way to handle fetch requests in React using the useEffect hook and the AbortController API. When making API calls within useEffect, it's important to clean up ongoing requests to prevent issues such as unnecessary network traffic, potential data conflicts, and memory leaks.
