side effects questions

Techniques for managing side effects in React include using the useEffect hook for handling async operations, leveraging custom hooks to encapsulate side effect logic, and using libraries like Redux Thunk or Redux Saga for complex side effects management.

Strategies for managing side effects in React functional components include using the useEffect hook for side effects that interact with the DOM or external systems, employing custom hooks to encapsulate side effect logic, and ensuring proper cleanup to prevent memory leaks.

`useEffect` is used to perform side effects in functional components, such as data fetching, subscriptions, or manually changing the DOM. It runs after the render is committed to the screen. By specifying dependencies, you can control when the effect runs. For example, fetching data from an API when a component mounts.
