Hooks in React JS.? Essential React Hooks.?

React Hooks are functions that let developers "hook into" React state and lifecycle features from function components. They were introduced in React version 16.8 to provide a more straightforward way to manage state and side-effects in functional components, allowing developers to use state and other React features without writing a class.

Here are some essential React Hooks.

useState is a Hook that allows functional components to manage state. It returns a stateful value and a function to update it

useEffect is a Hook that performs side effects in functional components. It's similar to componentDidMount, componentDidUpdate, and componentWillUnmount in class components.

useContext is a Hook that allows you to use values from React context without introducing nesting. It accepts a context object and returns the current context value.

useReducer is a Hook for managing more complex state logic in functional components. It's similar to useState, but it provides a more predictable way to manage the state by using a reducer function.

useCallback and useMemo are optimization Hooks. useCallback memoizes functions, and useMemo memoizes the result of a function. They are useful for preventing unnecessary re-rendering of child components.
