React hooks

In React, a component's lifecycle includes methods that are called at different stages of its life. These methods let you perform specific actions or side effects when the component is created, updated, or removed from the DOM

What are react hooks?

Hooks are functions that let you “hook into” React state and lifecycle features from function components. Hooks don't work inside classes — they let you use React without classes.

What is State in React?

In React, state is a built-in object that allows components to store data that may change over time. When the state changes, the component re-renders to reflect the updated data.

Benefits of using React Hooks

  1. Cleaner code:
    • Hooks make your code more concise and easier to read, especially for components with complex state logic.
  2. Better organization:
    • Hooks allow you to group related logic together, making your components more organized and maintainable.
  3. Improved reusability:
    • Hooks are just functions, so you can easily reuse them across different components.
