Node.js uses an event-driven, non-blocking I/O model to handle concurrent activity in a single-threaded environment.
Node.js uses an event loop to handle I/O operations asynchronously.
Callbacks are used to handle events and execute code when an event occurs.
Node.js also uses worker threads to handle CPU-intensive tasks in parallel.
The single-threaded nature of Node.js allows for efficient use of system resources.

setTimeout and setImmediate are async functions used to delay the execution of code.
setTimeout delays the execution of a function by a specified amount of time in milliseconds.
setImmediate schedules a function to be executed in the next iteration of the event loop.
Other async functions include setInterval, process.nextTick, and Promise.then.
These functions are useful for handling time-consuming tasks without blocking t
Promises and async are used for asynchronous programming in JavaScript.
Promises are objects that represent the eventual completion or failure of an asynchronous operation.
Async/await is a syntax for writing asynchronous code that looks like synchronous code.
Promises can be chained using .then() and .catch() methods.
Async functions always return a promise.
Example: fetching data from an API using promises and async/await

Node.js is a runtime environment that allows you to run JavaScript on the server side.
Node.js is built on Chrome's V8 JavaScript engine.
It is lightweight and efficient for building scalable network applications.
Node.js uses an event-driven, non-blocking I/O model, making it ideal for real-time applications like chat apps or streaming services.
NodeJs achieves multiple threading through event loop and asynchronous non-blocking I/O operations.
NodeJs uses event loop to handle multiple requests efficiently without blocking the main thread.
It utilizes asynchronous non-blocking I/O operations to perform tasks concurrently.
NodeJs can also create child processes to handle heavy computational tasks in parallel.
