Framework structure refers to the organization of code, libraries, and tools used in automation testing.
Framework structure typically includes folders for test scripts, test data, configuration files, and reusable components.
It also involves defining the hierarchy of test cases, setting up test suites, and implementing reporting mechanisms.
Common types of frameworks include data-driven, keyword-driven, and hybrid ...
Reading a file in Node.js involves using the 'fs' module to open and read the contents of the file.
Use the 'fs' module's 'readFile' method to read the contents of a file asynchronously.
Pass the file path and encoding as parameters to the 'readFile' method.
Handle the file contents in the callback function provided to the 'readFile' method.
I used React.js as the framework in my last project.
React.js is a popular JavaScript library for building user interfaces.
It allows for the creation of reusable UI components.
React.js uses a virtual DOM for efficient rendering.
Example: I used React.js to build a dynamic dashboard for tracking sales data.

React props are used to pass data from parent to child components in React applications.
Props are read-only and cannot be modified by the child component
Props are passed down from parent to child components
Props can be accessed using this.props in class components or props in functional components
React state is used to store and manage data within a component.
State is used to store data that can change over time within a component
State can be initialized in the constructor using this.state
State can be updated using this.setState() method
State changes trigger re-rendering of the component
Redux is a predictable state container for JavaScript apps, commonly used with React for managing application state.
Redux helps manage the state of an application in a predictable way
It uses a single immutable state tree which can only be changed by emitting actions
Reducers are pure functions that specify how the state changes in response to actions

useState is imported from React: `import React, { useState } from 'react';`
It initializes state in functional components: `const [count, setCount] = useState(0);`
The first element is the current state value, and the second is a function to update it.
State updates are asynchronous and can be batched for performance.
Example of updating state: `set...
useState manages state in functional components; useEffect handles side effects like data fetching and subscriptions.
