- Q1. About virtual DOM and it's implementation
- Q2. Implementation of map, reduce, filter
- Ans.
Map, reduce, and filter are higher-order functions commonly used in functional programming to manipulate arrays.
Map: Transforms each element in an array based on a provided function.
Reduce: Reduces an array to a single value by applying a function to each element.
Filter: Creates a new array with elements that pass a certain condition.
- Q3. Closures and their implementation
- Ans.
Closures are functions that have access to variables from their containing scope.
Closures can access variables from their outer function even after the outer function has finished executing.
Closures can be used to create private variables in JavaScript.
Closures are commonly used in event handlers and callbacks.
- Q4. Redux sagas and their practical use cases
- Ans.
Redux sagas are middleware libraries for managing side effects in Redux applications.
Redux sagas are used to handle asynchronous actions in Redux, such as API calls or timers.
They are implemented as generator functions that can pause and resume execution.
Redux sagas provide a more structured and testable approach to handling side effects compared to traditional Redux middleware like Thunk.

- Q1. What is node js?
- Ans.
Node.js is a runtime environment that allows you to run JavaScript code outside of a web browser.
Node.js is built on Chrome's V8 JavaScript engine.
It uses an event-driven, non-blocking I/O model.
Node.js is commonly used for building server-side applications.
It has a large ecosystem of open-source libraries and frameworks like Express.js.
- Q2. What is event loop?
- Ans.
Event loop is a mechanism that allows a program to efficiently handle multiple events or tasks concurrently.
Event loop is commonly used in asynchronous programming to manage tasks that may take varying amounts of time to complete.
It continuously checks for events or tasks in a queue and executes them one by one.
Event loop helps prevent blocking of the main thread by allowing non-blocking execution of tasks.

- Q3. Difference between callback and promise?
- Ans.
Callback is a function passed as an argument to another function to be executed later, while a promise is an object representing the eventual completion or failure of an asynchronous operation.
Callback is used in traditional asynchronous programming, while promises are used in modern asynchronous programming.
Callbacks can lead to callback hell or pyramid of doom, while promises provide better readability and error hand...
- Q4. What is middlewares in node js?
- Ans.
Middlewares in Node.js are functions that have access to the request and response objects, and can modify or terminate the request-response cycle.
Middlewares are functions that are executed in the middle of the request-response cycle.
They can perform tasks like parsing request data, logging, authentication, etc.
Middlewares can be added using app.use() method in Express framework.
Example: app.use(bodyParser.json()) to p
- Q5. What is event emitter?
- Ans.
Event emitter is a pattern used to handle and respond to events in software development.
Event emitter is a design pattern commonly used in Node.js for handling events.
It allows objects to subscribe to events and be notified when those events occur.
Event emitter is often used for asynchronous programming and decoupling components.
Example: EventEmitter class in Node.js can be used to create custom events and handle them.
