Why functional components are better than class components in React?
Easier to reuse: Functional components are easier to reuse than class components. Because they are just plain JavaScript functions, they can be easily reused across different parts of your application.Functional components achieve similar functionality using the useEffect hook, which can handle side effects and lifecycle events in a unified API. Performance: Functional components can be more performant due to their more superficial nature.Advantages of Functional Components vs Class Components

Easier to reuse and compose: Since they are just functions, you can easily extract logic into separate functions and reuse them in multiple components.

Why not to use class components in React : Functional components provide many advantages over class components in React. They are simpler, more performant, easier to test, work well with the hooks API, and are now the recommended way to write React components.

Are functions better than classes

If you're dealing with simpler tasks or functional programming paradigms, functions may suffice. However, if you need to model more complex entities, encapsulate state, or implement inheritance, classes provide a more structured and organized approach.

What is your opinion on picking the class or functional components as per the requirement : Simplicity and Readability: Functional components are often simpler and easier to read than class components. They focus on rendering UI, resulting in cleaner code. No Boilerplate: Functional components eliminate the need for constructor methods and class boilerplate, reducing code complexity.

As you can see, the function component requires fewer lines of code, making it more readable and less error-prone. Function components offer better performance than class components. This improvement is due to the introduction of React Hooks, which allow function components to manage state and side effects efficiently.

Cons of Functional Components:

The syntax is a little difficult to understand for those who are used to the Class model. Stateful logic should ideally be separated out from Functional components and hence not making it reusable as a complete unit. For complex components, code is harder to understand due to decoupling.

What are three 3 benefits of functional programming

7 Unbeatable Advantages of Functional Programming

  • Use of Pure Functions. Pure functions always produce the same output and have no external values affecting the end result.
  • Optimum Transparency.
  • Lazy Evaluation.
  • Enhanced Readability.
  • Static Variables.
  • Seamless Parallel Programming.
  • Validating Functional Signatures.
  • Conclusion.

Class Components in React are like the older, more formal way of building things. They involve more code and can be a bit complex compared to the newer, simpler functional components. Think of them as the traditional way of doing things in React.Conclusion: React offers both class components and functional components as two approaches for building reusable UI elements. Class components are more suitable for complex logic and advanced features, whereas functional components with hooks provide simplicity, performance, and ease of use.

As you can see, the function component requires fewer lines of code, making it more readable and less error-prone. Function components offer better performance than class components. This improvement is due to the introduction of React Hooks, which allow function components to manage state and side effects efficiently.

Which is faster class or function : No, classes are not slower than functions because classes and functions are effectively the same thing. Classes consist of functions and variables packaged into one software unit.

Do you prefer function based or class component and why : As we can see, Functional components are leaner and more flexible. It's easier to work with state because we have React hooks that help handle state and side effects. If you're building error boundaries, then you should work with Class components.

Which is better class or functional component

Ans: Functional components are simpler, faster, and lack state or lifecycle methods, making them ideal for small, presentational components. In contrast, class components are more complex, support state and lifecycle methods, and are suitable for larger, reusable components.Functional Components vs Class Components

Functional Components Class Components
Functional components are more efficient Class components are a little inefficient
Functional components require fewer lines of code and are easy to understand Class components are complex and require more lines of code.

What is the biggest weakness of a Functional structure : it cannot operate efficiently in a stable environment.
