React Functional Components vs React Class Components

Developers should learn and use React Functional Components because they are the standard in current React applications, offering better performance and cleaner code compared to class components meets developers should learn react class components when working on legacy react applications, as many existing projects still use them, and understanding them is crucial for maintenance and migration. Here's our take.

React Functional Components

Nice Pick

Developers should learn and use React Functional Components because they are the standard in current React applications, offering better performance and cleaner code compared to class components

Pros

• Related to: react-hooks, jsx

Cons

• Specific tradeoffs depend on your use case

React Class Components

Developers should learn React Class Components when working on legacy React applications, as many existing projects still use them, and understanding them is crucial for maintenance and migration

Pros

• They are also useful for grasping fundamental React concepts like lifecycle methods and state management, which underpin newer Hook-based approaches
• Related to: react-hooks, react-functional-components

Cons

• Specific tradeoffs depend on your use case
