1 - What is React JS? React JS is a free and open source front end library for building user interfaces. It uses a declarative approach to creating components, making code more maintainable and easier to debug.
2) What are the key concepts of React JS? Key concepts include: components, props, state, and the virtual DOM.
3) What is a component in React JS? Components are reusable building blocks that make up the UI. They can be as simple or complex as needed.
4) What are props in React JS? Props are properties that are passed to a component from its parent. They allow for data flow between components.
5) What is state in React JS? State is the internal data of a component that can change over time. It allows for the UI to be updated dynamically.
6) What is the virtual DOM in React JS? The virtual DOM is a lightweight representation of the UI that React maintains. It is used to efficiently update the real DOM when changes occur.
7) What are the advantages of using React JS? React JS offers advantages such as increased code reusability, improved performance, and a declarative approach to UI development.
8) What is the difference between class components and functional components in React JS? Class components use ES6 classes and have access to state and lifecycle methods, while functional components are simpler and use hooks for state management.
9) What are hooks in React JS? Hooks are functions that allow you to access state and lifecycle methods in functional components.
10) What is the Flux pattern in React JS? Flux is a pattern for managing data flow in complex React applications.
11 - What is Redux in React JS? Redux is a state management library that helps organize state and actions in React applications.
12) What are some best practices for using React JS? Best practices include using components effectively, managing state properly, and following naming conventions.
13) What are some common pitfalls to avoid when using React JS? Common pitfalls include overusing state, neglecting performance optimization, and creating overly complex components.
14) What are the future trends in React JS? Future trends include the continued adoption of hooks, the use of AI in development, and the integration of React with other technologies.
15) What are some resources for learning React JS? There are numerous online courses, tutorials, and documentation available for learning React JS.
