Hooks in React are special functions introduced in React 16.8 that allow you to use state and other React features in functional components, without writing class components.

Error Boundaries are a React feature used to catch JavaScript errors in the component tree and prevent the whole app from crashing. They are a very common interview question, especially for React mid-level roles.

In React interviews, this is a very common concept because it tests your understanding of form handling and state management.

A Higher Order Component (HOC) is a function that takes a component and returns a new component with enhanced behavior.

Memoization in React is an optimization technique used to avoid unnecessary re-computations or re-renders by caching the result of expensive operations and reusing it when the same inputs occur again.

A Pure Component is a class component in React that only re-renders when there is a change in props or state with a shallow comparison.

In React, shouldComponentUpdate() is a lifecycle method used in class components to control whether a component should re-render when it receives new props or state.

componentDidMount() is a lifecycle method in React class components. It is called once immediately after the component is rendered (mounted) into the DOM.

In React, a component goes through different lifecycle phases from the time it is created until it is removed from the UI.
