Should I use functional or class components?
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.We recommend defining components as functions instead of classes. See how to migrate. Component is the base class for the React components defined as JavaScript classes. Class components are still supported by React, but we don't recommend using them in new code.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.

Why functional components are better in performance : 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.

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.

You Don't Need to Learn Class Components

This is no longer necessary to learn as a React developer, but it can still benefit you to learn it. After the introduction of a feature called React hooks in 2018, React developers have moved over to using function components, which are made with JavaScript functions.

Functional components can be more efficient than class components because they do not have the overhead of creating an instance of a class. This can result in faster rendering and a smoother user experience. Functional components are also easier to test than class components.

No. There are no plans to remove classes from React — we all need to keep shipping products and can't afford rewrites. We recommend trying Hooks in new code.

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.Observed behavior

mutating a simple class instance is 5x slower than equivalent plain JS Object. 5x is significant.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.

Are React class components going away : Class components are still supported, but the React team recommends using functional components for new development as they provide a simpler and more concise way of building React applications. From React documentation: "Component is the base class for the React components defined as JavaScript classes.

Why not to use class components

Functional components can be more efficient than class components because they do not have the overhead of creating an instance of a class. This can result in faster rendering and a smoother user experience. Functional components are also easier to test than class components.

One of the main drawbacks is their complexity. Class components have a steeper learning curve compared to functional components, especially for developers who are new to React. The syntax and concepts used in class components, such as the use of this and the lifecycle methods, can be confusing for beginners.Class components are still supported, but the React team recommends using functional components for new development as they provide a simpler and more concise way of building React applications. From React documentation: "Component is the base class for the React components defined as JavaScript classes.

Do people still use React classes : With the rise of functional components and hooks in React, class components have taken a backseat in modern React development. However, there are still scenarios where class components offer advantages over functional components.
