- 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 that makes it lightweight and efficient.
Node.js is commonly used for building server-side applications and APIs.
It has a large ecosystem of open-source libraries and frameworks, such as Express.js.
- Q2. What is middleware
- Ans.
Middleware is a software component that acts as a bridge between an application's request and response.
Middleware functions have access to the request and response objects
They can modify the request and response objects
Middleware can be used for tasks like authentication, logging, error handling, etc.
- Q3. What is promise
- Ans.
A promise is an object representing the eventual completion or failure of an asynchronous operation.
Promises are used to handle asynchronous operations in JavaScript.
They can be in one of three states: pending, fulfilled, or rejected.
Promises can be chained using .then() to handle success and .catch() to handle errors.
Example: new Promise((resolve, reject) => { setTimeout(() => resolve('Done!'), 1000); });
- Q4. What is promise.all
- Ans.
promise.all is a method in JavaScript that takes an array of promises and returns a single promise that resolves when all of the input promises have resolved.
Used to handle multiple asynchronous operations at once
Returns a single promise that resolves when all input promises have resolved
If any of the input promises is rejected, the returned promise is rejected with the reason of the first rejected promise
- Q5. What is callback
- Ans.
A callback is a function passed as an argument to another function to be executed later.
Callbacks are commonly used in asynchronous programming to handle tasks that take time to complete.
They are often used in event handling, timers, and AJAX requests.
Callbacks can be synchronous or asynchronous, depending on when they are executed.
Example: setTimeout(callback, 1000) will execute the callback function after 1 second.
