Function Components vs Class Components

Function components have become more popular than class components in React for several reasons:

1. Simplicity & Readability

Function components are more concise and easier to read compared to class components. They require less boilerplate code, making development faster and reducing the chances of errors.

2. Performance Improvements

Function components generally perform better because they avoid unnecessary re-renders and memory overhead associated with class components. React optimizes function components more efficiently.

3. React Hooks

With the introduction of React Hooks (useState, useEffect, etc.), function components gained the ability to manage state and lifecycle methods without needing a class. This made them more powerful and flexible.

4. Better Reusability & Composition

Function components encourage a more modular approach, making it easier to reuse and compose components. Hooks allow developers to extract logic into reusable functions, improving maintainability.

5. Future-Proofing

React’s development is increasingly focused on function components and hooks. Many new features and optimizations are designed with function components in mind, making them the preferred choice for modern React applications.
