This is a common interview question ask to beginners during interview, through this post will try to answer the question in the simplest manner and in short manner that can be helpful during interview
What is React ?
React is an open-source JavaScript library that is used for building user interfaces (UI) and single-page applications (SPA). Developed by Facebook, React has quickly become one of the most popular front-end development tools.
Now if you want to earn some brownie point in interviews you can use some hardcode word like virtual dom in explaining what react is, an example like below
React is a declarative, component-based library that allows developers to create complex user interfaces with ease. React makes use of a virtual DOM (Document Object Model) which is a lightweight representation of the actual DOM. The virtual DOM allows React to efficiently update and render changes in the UI, resulting in faster and smoother user experiences.
Why to Use React?
React offers a number of benefits for front-end developers. Some of the key advantages of using React include:
- Reusability: React components are reusable and can be used across multiple projects, making it easier to maintain and update code.
- Scalability: React is highly scalable and can be used to build large, complex applications.
- Performance: React’s virtual DOM makes it fast and efficient, resulting in better performance and faster load times.
- Community: React has a large and active community of developers who contribute to the library and provide support.
If u able to say this much also then its more than enough to satisfy the interviewer.
