Promises are used for asynchronous operations that return a single value, while observables are used for asynchronous operations that return multiple values over time.
Promises return a single value and are not cancellable.
Observables return multiple values over time and can be cancelled.
Promises are eager and start executing immediately upon creation.
Observables are lazy and do not execute until subscribed to.
Promises ...
Services are a way to share data and functionality across components in Angular.
Services are singleton objects that can be injected into components.
They provide a way to share data and functionality across components.
They can be used to make HTTP requests, handle authentication, and more.
Services can be generated using the Angular CLI.
They are typically defined in a separate file and imported into components.
ng-content is a directive in Angular that allows for dynamic insertion of content.
It is used to project content into a component from the outside.
It is often used in combination with ng-template and ng-container.
It can be used to create reusable components that can be customized with different content.
It is useful for creating layouts and templates that can be reused across multiple components.
Dependency Injection is a design pattern used to inject dependencies into a class or component.
DI is used to reduce coupling between components
It allows for easier testing and maintenance
Angular has its own DI system built-in
Services and providers are commonly used with DI

I applied via Approached by Company and was interviewed in Jan 2024. There was 1 interview round.
Map, reduce, and filter are higher-order functions in JavaScript used to manipulate arrays.
Map: Transforms each element in an array and returns a new array with the transformed elements.
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.

I applied via Walk-in and was interviewed before Jun 2023. There was 1 interview round.
An interface in software development defines a contract for classes to implement, specifying methods and properties.
Interfaces in programming languages like Java and C# allow for multiple inheritance by defining a set of methods that a class must implement.
Interfaces provide a way to achieve abstraction and polymorphism in object-oriented programming.
Interfaces are used to define common behavior that multiple classes c...
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit.
Encapsulation helps in hiding the internal state of an object and restricting access to it.
It allows for better control over the data by preventing direct access from outside the class.
Encapsulation promotes code reusability and makes the code easier to maintain.
Example: In a class representing a car, the variables lik...

OOPs concepts in Java include inheritance, polymorphism, encapsulation, and abstraction.
Inheritance allows a subclass to inherit properties and methods from a superclass.
Polymorphism allows objects to take on multiple forms and behave differently based on their context.
Encapsulation hides the implementation details of an object and only exposes necessary information.
Abstraction allows for the creation of abstract class...
Interfaces define contracts for behavior, while inheritance allows for code reuse and polymorphism.
Interfaces allow for loose coupling and abstraction, enabling multiple implementations of the same behavior.
Inheritance allows for code reuse and extension of existing classes, reducing code duplication.
Polymorphism allows objects of different classes to be treated as if they were of the same class, simplifying code and i
SQL query for joining tables
Use JOIN keyword to combine two or more tables based on a related column
Specify the columns to be selected using SELECT keyword
Use ON keyword to specify the condition for joining the tables
Different types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN
Used Java concepts such as inheritance, polymorphism, and exception handling in my project.
Implemented inheritance to create a base class and derived classes with specific functionalities.
Utilized polymorphism to allow objects of different classes to be treated as if they were of the same class.
Implemented exception handling to handle errors and prevent program crashes.
Used interfaces to define a set of methods that a ...
Overloading is having multiple methods with the same name but different parameters. Overriding is having a method in a subclass with the same name and parameters as a method in the superclass.
Overloading is used to provide different ways to call a method with different parameters
Overriding is used to provide a specific implementation of a method in a subclass
Overloading is resolved at compile-time while overriding is r...
=== compares value and type, while == only compares value
=== is stricter than == in type checking
=== returns true only if both operands are of the same type and have the same value
== performs type coercion, which can lead to unexpected results
For example, '5' == 5 returns true, but '5' === 5 returns false
