Event Loop is a mechanism in Node.js that allows non-blocking I/O operations to be performed asynchronously.
Event Loop is responsible for handling asynchronous operations in Node.js.
It allows Node.js to perform I/O operations without blocking the execution of other code.
Event Loop continuously checks the event queue for new events and executes them in a loop.
It helps in achieving high performance and scalability in Nod
My favorite sorting mechanism is Quick Sort.
Quick Sort is a divide-and-conquer algorithm that recursively divides the array into smaller subarrays.
It has an average time complexity of O(n log n) and is efficient for large datasets.
Example code snippet: function quickSort(arr) { if (arr.length <= 1) { return arr; } const pivot = arr[arr.length - 1]; const left = []; const right = []; for (let i = 0; i < arr.length...

Use load balancing to distribute incoming requests across multiple servers.
Implement caching to store frequently accessed data and reduce database load.
Optimize code for performance by identifying and fixing bottlenecks.
Scale horizontally by...
Closures are functions that have access to variables from their containing scope even after the scope has closed.
Closures allow for data encapsulation and privacy in JavaScript.
They are commonly used in event handlers, callbacks, and modules.
Example: A counter function using closures to maintain its state.

Closures are functions that have access to variables from their containing scope even after the scope has closed.
Closures allow functions to access variables from their outer function even after the outer function has finished executing.
They are commonly used in event handlers, callbacks, and asynchronous programming.
Closures help in maintaining state in functional programming.
Virtual DOM is a lightweight copy of the actual DOM used for efficient updates in web development.
Virtual DOM is a concept used in frameworks like React to improve performance by minimizing actual DOM manipulations.
When changes are made to the virtual DOM, a comparison is done with the actual DOM to determine the minimal updates needed.
This approach reduces the number of costly DOM operations, resulting in faster rende
Data types in JavaScript include number, string, boolean, object, function, undefined, and null.
Number - represents numeric data, e.g. 10, 3.14
String - represents textual data, e.g. 'hello', '123'
Boolean - represents true or false values, e.g. true, false
Object - represents complex data structures, e.g. { key: 'value' }
Function - represents executable code, e.g. function() { }
Undefined - represents a variable that has ...

OOPs (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
OOPs focuses on creating objects that interact with each other to solve a problem
Encapsulation: Objects encapsulate data and behavior. Example: Car object with properties like color and methods like start()
Inheritance: Objects can inherit attributes and methods from other objects. Example: Anima...
Data structures are ways to organize and store data efficiently in a computer.
Data structures are used to store and organize data in a way that makes it easy to access and manipulate.
Examples of data structures include arrays, linked lists, stacks, queues, trees, and graphs.
For example, an array is a data structure that stores a collection of elements in a contiguous block of memory.
A linked list is a data structure wh...
