React Functional 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

Pros

• They are essential for leveraging React Hooks (like useState, useEffect) to handle state, lifecycle events, and side effects, which simplifies complex logic and reduces boilerplate
• Related to: react-hooks, jsx

Cons

• Specific tradeoffs depend on your use case
