Ans: The advantages of ReactJS are: Increases the application’s performance with Virtual DOM JSX makes code easy to read and write It renders both on the client and server-side Easy to integrate with other frameworks (Angular, BackboneJS) since it is only a view library Easy to write UI Test cases and integration with tools such as JEST.

2: What do you understand about Virtual DOM?

Ans: A virtual DOM is a lightweight JavaScript object which originally is just a copy of the real DOM. It is a node tree that lists the elements, their attributes, and content as objects and their properties. React render function creates a node tree out of the React components.

8: What do you know about Dependency Injection?

Ans: Dependency injection is utilised for separating the client creation dependencies from behaviour, which lets you design a slackly coupled program. It also allows the modification of the behaviour of applications by using the components.

9: What is CallBack Hell?

Ans: A CallBack Hell is a condition, It occurs when many asynchronous functions are chained together. The asynchronous function expects a callback, as it is a return parameter.

10: What is Mongoose?
