The async/await pattern was introduced to simplify asynchronous programming by making asynchronous code look and behave more like synchronous code. Here’s how it evolved across different programming languages.
Functional programming (FP) is a paradigm that emphasizes immutability, pure functions, and higher-order functions. While Python, Java, and C# are all multi-paradigm languages (supporting both object-oriented and functional programming), they each have different levels of FP support. Here’s a comparison: 1. First-Class Functions All three languages support first-class functions, meaning functions can be assigned to variables, passed as arguments, and returned from other functions. Python: Full support for first-class functions using lambda, map(), filter(), reduce(), and list comprehensions. Java: Added functional support in Java 8 with lambda expressions and the Stream API. C#: Supports functional programming via delegates, lambda expressions, and LINQ (Language Integrated Query). 2. Higher-Order Functions A function is considered higher-order if it takes another function as an argument or returns one. ...
