Cases when React Hooks does not work

1. Using Hooks inside a class component: React Hooks are designed to be used in functional components. They cannot be used inside class components. If you have a class component and want to leverage the benefits of Hooks, you will need to refactor your component into a functional component.
2. Using Hooks conditionally: React Hooks should always be used at the top level of a functional component. If you try to use Hooks conditionally, such as inside an if statement or a loop, it will lead to unexpected behavior. Hooks should always be called in the same order on every render to ensure consistent state management.
3. Using Hooks in a different order: The order in which Hooks are called matters, as they rely on the order to maintain a consistent state. If you change the order of Hooks within a component, it can lead to bugs and incorrect state management. Make sure to always call Hooks in the same order on every render.
4. Using Hooks outside of a functional component: Hooks are meant to be used within functional components. If you try to use Hooks outside of a functional component, such as in a regular JavaScript function or an event handler, it will result in an error. Hooks should only be called within the body of a functional component.
5. Using Hooks before the component is mounted: Hooks can only be used inside mounted components. If you try to use Hooks before the component is mounted, such as in the initialization phase or in a conditional statement that prevents the component from rendering, it will result in an error. Hooks should be used within components that are mounted and rendered to the DOM.
6. Using Hooks in non-React functions: Hooks are designed to work with React components and React’s rendering cycle. If you try to use Hooks in non-React functions, such as utility functions or external libraries, it will result in an error. Hooks should only be used within React components.

Pros & cons of React Hooks

6 Pros of React Hooks

• Improved code organization: React Hooks allow you to write functional components that are easier to read and maintain. With Hooks, you can logically group related code together, making it easier to understand and modify.
• Reusability: Hooks promote code reuse by allowing you to extract and share stateful logic between components. This reduces code duplication and improves overall development efficiency.
• Simplified component lifecycle: With Hooks, you can handle component lifecycle events, such as mounting, updating, and unmounting, within functional components. This eliminates the need for class components and simplifies the component lifecycle management.
• Better performance: Hooks enable you to optimize the performance of your React applications. By using memoization techniques and avoiding unnecessary re-renders, Hooks can improve the overall rendering performance.
• Improved testing: Testing functional components that use Hooks is easier compared to testing class components. With Hooks, you can easily mock state and simulate component behavior, leading to more comprehensive and reliable tests.
• Easy to learn: React Hooks provide a simpler and more intuitive way of working with state and side effects. They have a smaller API surface area compared to class components, making it easier for developers to learn and adopt Hooks.

6 Cons of React Hooks

• Legacy code compatibility: React Hooks were introduced in React 16.8, so if you have an existing codebase built on older versions, it may require significant refactoring to adopt Hooks.
• Learning curve: Although React Hooks are designed to be easy to learn, developers who are already familiar with class components may need to invest time in understanding the new paradigm and best practices.
• Breaking changes: As React Hooks are relatively new, there is a possibility of breaking changes in future releases. This means that you may need to update your codebase to adapt to these changes.
• Less community support: While React Hooks have gained popularity, the ecosystem and community support for Hooks might not be as extensive as it is for class components. This can result in fewer resources and libraries specifically tailored for working with Hooks.
• Possible performance issues: Incorrect usage of React Hooks can lead to performance issues, such as unnecessary re-renders or inefficient state management. It’s important to understand the best practices and guidelines for using Hooks to avoid such issues.
• Dependency on React version: React Hooks are tied to specific versions of React. If you need to use an older version of React for compatibility reasons, you may not be able to leverage the benefits of Hooks.

TOP 15 Facts about React Hooks

• React Hooks is a feature introduced in React 16.8 that allows developers to use state and other React features without writing a class.
• Unlike class components, React Hooks are functions that can be used inside functional components.
• React Hooks provide a way to reuse stateful logic across components without the need for higher-order components or render props.
• The useState Hook is one of the most commonly used React Hooks. It allows developers to add state to functional components by declaring a state variable and a function to update it.
• The useEffect Hook is another widely used React Hook that allows developers to perform side effects in functional components. Side effects can include fetching data, subscribing to events, or manually changing the DOM.
• React Hooks follow the rules of Hooks, which enforce specific ordering and usage guidelines to ensure consistent behavior.
• With React Hooks, components can be written in a more functional and declarative style, making them easier to understand and test.
• React Hooks can help improve the performance of components by allowing developers to optimize the re-rendering process through the use of memoization and other techniques.
• The useContext Hook allows components to consume values from a context without the need for a higher-order component or a consumer component.
• React Hooks can simplify the handling of form inputs by providing Hooks like useState and useEffect to manage the state and side effects associated with form fields.
• React Hooks can be used with TypeScript, providing type safety and helping catch potential errors during development.
• The useReducer Hook is an alternative to useState that allows for more complex state management. It is particularly useful when dealing with state that involves multiple related values or when the next state depends on the previous one.
• React Hooks can be used in custom Hooks, which allows developers to create reusable pieces of stateful logic that can be shared across multiple components.
• React Hooks can be combined with libraries like Redux or MobX to integrate state management solutions into functional components.
• React Hooks have gained significant popularity since their introduction, with many developers embracing their simplicity and improved developer experience.

How and where is React Hooks used?
