Event Loop in JavaScript manages asynchronous operations by executing callback functions in a non-blocking way.

• Event Loop continuously checks the call stack and the callback queue.

• It moves tasks from the callback queue to the call stack when the call stack is empty.

• This allows JavaScript to handle asynchronous operations without blocking the main thread.

• Example: setTimeout() function adds a task to the callback queue after a specified delay.

Servlets are Java classes that handle HTTP requests and responses, while models are Java classes that represent data and business logic.

• Servlets are used to handle HTTP requests and responses in web applications.

• Models are used to represent data and business logic in web applications.

• Servlets are part of the presentation layer, while models are part of the business layer.

• Servlets are typically used to interact with the user interface, while models are used to interact with th...read more

Remove duplicates from an array of strings

• Iterate through the array and use a set to keep track of unique strings

• If a string is already in the set, remove it from the array

• Return the modified array without duplicates

C# 9.0 introduces new features like records, init-only setters, and top-level statements.

• Records provide a concise syntax for defining immutable types.

• Init-only setters allow setting properties only during object initialization.

• Top-level statements allow writing code without a class or namespace.

• Improved pattern matching with logical patterns and relational patterns.

• Function pointers and improved support for native interop.

• New target-typed expressions and covariant returns.

Framework architecture defines the structure, components, and interactions within a software framework.

• Modularity: Frameworks are built with modular components, allowing for easy updates and maintenance. Example: Microservices architecture.

• Reusability: Code can be reused across different projects, reducing development time. Example: Libraries like React for UI components.

• Extensibility: Frameworks allow developers to extend functionality without modifying core code. Example: P...read more

Tree and graph traversal algorithms are used to visit each node in a tree or graph structure in a systematic way.

• Depth-first search (DFS) and breadth-first search (BFS) are commonly used algorithms for tree and graph traversal.

• DFS explores as far as possible along each branch before backtracking, while BFS explores the neighbor nodes first.

• In-order, pre-order, and post-order traversals are used for binary trees to visit nodes in a specific order.

• Dijkstra's algorithm and A* se...read more

Delegate is a type that holds a reference to a method, while an event is a mechanism for communication between objects.

• Delegate is a type that can hold a reference to a method, while an event is a mechanism for communication between objects.

• Delegates are used to implement callbacks and event handlers, while events are used to notify subscribers when something happens.

• Delegates can be multicast, meaning they can hold references to multiple methods, while events can only have o...read more

The kernel manages system resources, facilitating communication between hardware and software components.

• Resource Management: The kernel allocates CPU time, memory, and I/O devices to processes.

• Process Scheduling: It uses algorithms like Round Robin or Priority Scheduling to manage process execution.

• Memory Management: The kernel handles memory allocation and deallocation, using techniques like paging and segmentation.

• Device Drivers: It provides an interface for hardware devic...read more

Workflows are a series of steps that define a process. They help to streamline work and ensure consistency.

• Workflows are used to automate processes and reduce errors

• They can be used in various industries such as healthcare, finance, and manufacturing

• Workflows can be visualized using flowcharts or diagrams

• They can be customized to fit specific needs and requirements

• Examples of workflows include employee onboarding, invoice processing, and patient care management

Implementing polyfills for Promises to ensure compatibility in environments lacking native support.

Solid Principles are a set of five design principles for writing clean, maintainable, and scalable code.

• Single Responsibility Principle: A class should have only one reason to change.

• Open/Closed Principle: Classes should be open for extension but closed for modification.

• Liskov Substitution Principle: Objects of a superclass should be replaceable with objects of its subclasses without affecting the program's correctness.

• Interface Segregation Principle: Clients should not be fo...read more

Web Components are a set of web platform APIs that allow you to create new custom, reusable, encapsulated HTML tags to use in web pages and web apps.

• Shadow DOM provides encapsulation for the custom elements, ensuring that styles and scripts do not affect other parts of the document.

• HTML Templa...read more

Implementing Promise.all allows multiple promises to run concurrently and resolves when all promises are fulfilled.
