Angular is a front-end framework while Node.js is a back-end runtime environment.
Angular is used for building dynamic web applications with a focus on the client-side.
Node.js is used for building server-side applications with JavaScript.
Angular uses TypeScript for building applications while Node.js uses JavaScript.
Angular has a large community and a lot of pre-built components while Node.js has a vast library of modul...
I applied via Campus Placement and was interviewed in Jul 2023. There were 3 interview rounds.
Binary search is a fast search algorithm that finds the position of a target value within a sorted array.
Binary search works by repeatedly dividing the search interval in half.
It compares the target value with the middle element of the array.
If the target value is equal to the middle element, the position is found.
If the target value is less than the middle element, the search continues on the lower half of the array.
I...
Quick sort is a popular sorting algorithm that uses divide and conquer strategy.
Divide the array into two sub-arrays based on a pivot element
Recursively sort the sub-arrays
Combine the sorted sub-arrays to get the final sorted array
I appeared for an interview before Mar 2024, where I was asked the following questions.
MVC lifecycle involves Model, View, and Controller interactions, while deployment ensures the application is live and accessible.
1. Model: Represents data and business logic. Example: A User model that interacts with a database.
2. View: Displays data to the user. Example: HTML templates rendering user information.
3. Controller: Handles user input and updates the model. Example: A login controller processing user creden...
CTE stands for Common Table Expression, a temporary result set in SQL used for complex queries.
CTE is defined using the WITH clause.
It can be recursive or non-recursive.
Example syntax: WITH CTE_Name AS (SELECT column1 FROM table) SELECT * FROM CTE_Name;
CTEs improve readability and organization of SQL queries.
They can be referenced multiple times within a query.
CORS is a security feature that allows restricted resources on a web page to be requested from another domain outside the domain from which the resource originated.
CORS is implemented via HTTP headers that allow servers to specify who can access their resources.
For example, a web application on 'example.com' can request resources from 'api.example.com' if CORS is enabled.
The 'Access-Control-Allow-Origin' header is cruc...
Bundling and minification optimize web assets by reducing file size and number of requests, improving load times and performance.
Bundling combines multiple files (e.g., JavaScript, CSS) into a single file to reduce HTTP requests.
Minification removes unnecessary characters (like whitespace and comments) from code to decrease file size.
Example of bundling: Combining 'script1.js', 'script2.js', and 'script3.js' into 'bund...
HTML helpers are functions that simplify the generation of HTML markup in web applications, enhancing code readability and maintainability.
HTML helpers are often used in MVC frameworks to generate HTML elements easily.
Common HTML helpers include methods for creating forms, links, and other UI components.
Example: In ASP.NET MVC, Html.TextBoxFor() generates an input element for a model property.
HTML helpers promote DRY (...

Promises are objects representing the eventual completion or failure of an asynchronous operation.
Promises are used in JavaScript to handle asynchronous operations.
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: Fetching data from an API returns a Promise that resolves with the data or rejects with an erro
Node.js is single threaded, but uses multiple threads for I/O operations.
Node.js uses a single thread to handle all JavaScript code execution.
It uses multiple threads from a thread pool to handle I/O operations asynchronously.
This allows Node.js to handle high concurrency without blocking the main thread.
Example: When reading a file, Node.js will use a separate thread from the pool to perform the I/O operation.
Reverse the Array of Strings
OOPS features include encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit (class).
Inheritance: Ability to create new classes based on existing classes, inheriting their attributes and methods.
Polymorphism: Ability to use a single interface for different data types or classes.
Abstraction: Hiding the implementation details and show
Interface is a contract that defines the methods a class must implement, while abstract class can have both implemented and abstract methods.
Interface methods are public and abstract by default, while abstract class can have abstract and non-abstract methods.
A class can implement multiple interfaces but can only inherit from one abstract class.
Interfaces are used for full abstraction, while abstract classes are used fo...
