Hooks are the latest addition in React version 16.8. It allows you to use state and related React features without writing a class. React is known as a library function for building user interfaces. One of its major benefits is that its library functions forcefully applies strict data flow to the developer. Whereas with a j Query it is nearly impossible to structure a project, it has to be defined in a way, to allow data flow across the User Interface. This makes it difficult to trace what function is changing what part of the User Interface. Such problems have been somewhat solved through React by imposing a clear structure and a strict data flow to develop a well-reasoned User Interface logic. In React 16.8, we get Hooks. That does not mean that classes will not work and even does not mean that classes will be deplored. It is conveyed by the React core team that, there are some limitations and not all the features of classes are addressed, but those will be upgraded in the later version soon.

It is hard reusing stateful logic between components:

React doesn’t offer a path to attach reusable behavior to the component. If you have been working on React, you should be familiar with different patterns like render props and high order components that try to resolve this. But these patterns allow you to estructure your program components while you are using them, which could be complicated and make the code hard to follow. If you take a look at a typical React application in React Dev Tools, you will find various wrapper hell components that are surrounded by layers, consumers, high order components, render props and many other abstractions. With the Hooks, you can extract stateful logic from a component, which further could be tested independently and reused. Hooks let you reuse stateful logic without making a change in your component hierarchy. This makes it more easy to share the Hooks among many other components.

Complex components are hard to understand:

complex components are hard to understand. We often have to manage components that began with simple but got complex through stateful logic statements. Each life cycle procedure contains a mix of unrelated logic. In many cases, it is not even possible to detached these components into small ones as its stateful logic is placed all over. It is difficult to test them. This is one of the reasons many people prefer to merge React with a separate state of management library.Henceforth, it introduces a lot of abstraction that may require you to take a leap towards different files and make the procedure of reusing the component more complicated. To provide a solution on this, Hooks allows you to split one component into smaller functions, this will be based on what pieces of components are required rather than splitting the complete life cycle method.

Classes confusing both human and machines:

To reuse code, organizing codes happen to form a complex situation. It is also found that making the right usage of classes can form a huge barrier in learning React. It is important to understand how it works in JavaScript, and later understanding its working on other
languages too. You have to be conscious of binding event handlers. Without unbalanced syntax proposals, the used codes would be more of a wordy, that is it won’t determine the proper syntax. This difference between class and components in React may create huge
confusion and using this may further lead to disagreements even between experienced React developers.
Additionally, React has been out for about five years, and we need to make sure it stays relevant until the next five years. As Svelte, Angular, Glimmer, and many more stands unique in their ways of command, compilation and execution of components, it has a lot of potential in the future. Conceptually, React components are always close to the functions. Hooks hold the functions without leaving the practical presence of React. Therefore it offers access to imperative escape hatches and doesn’t make you learn complex functions.
