1 - Importance of state management in React:
It enables centralized control over component state, reducing complexity and ensuring data consistency.
2) Difference between class and functional components:
Class components have a lifecycle method and state, while functional components are simpler and stateless, updated using hooks.
3) Optimization techniques in React:
Virtual DOM, memoization, code splitting, lazy loading, and performance profiling.
4) Explain React's context API:
A way to manage global state without passing props through multiple levels of a component tree.
5) Lifecycle methods in React:
Mounting: componentDidMount, componentWillMount (deprecated)
Updating: componentDidUpdate, shouldComponentUpdate (deprecated)
Unmounting: componentWillUnmount
6) Explain the Redux architecture:
A state management library that uses a single store to hold the application's state, with actions to modify it.
7) Explain props and their usage in React:
Props are immutable properties passed down from a parent component to its child components.
8) Describe the “lifting state up” principle:
Moving shared state to the nearest common ancestor of components that use it, improving reusability and data accessibility.
9) Explain the use of React hooks:
Functions that provide access to React features, such as useState and useEffect, without using class components.
10) Describe the benefits of using a component library in React:
Reusability, consistency, and increased development speed.
11 - Explain the role of React Router:
A library that manages client side routing, allowing users to navigate between different views.
12) Discuss the importance of performance optimization in React:
Ensures a smooth user experience, especially for complex applications.
13) Explain the concept of uncontrolled components:
Components whose state is controlled by the DOM input, rather than the component's state.
14) Describe React's approach to rendering:
Uses a virtual DOM to represent the component tree, optimizing updates by only re rendering the affected parts.
15) Explain the difference between React and Vue:
React is a library focused on building UIs using components, while Vue is a framework that includes UI rendering, state management, and other features.
