Debouncing — emit after silence Debouncing delays emitting a value until a specified period of inactivity. It's best for typeahead inputs where only the final value after the user stops typing is relevant.

Comprehensive Guide to C# and .NET Core OOP Concepts Class A class is a blueprint for creating objects that encapsulate both data and behavior. Access Modifiers : public, internal, abstract, sealed control visibility and inheritance. Static Classes : Cannot be instantiated, contain only static members. Partial Classes : Split across files using partial keyword for better organization. public class Car { public string Model; public void Drive() => Console.WriteLine($"{Model} is driving."); } Analogy: A car blueprint used to build many actual cars. Benefits: Reusability, Encapsulation, Abstraction, Inheritance Object An object is an instance of a class. Managed by Garbage Collector for automatic memory cleanup. Boxing/Unboxing allows value types to be treated a...
