Asynchronous Programming Cheat Sheet
A concise guide to asynchronous programming concepts, tools, and best practices, covering various languages and frameworks.
Core Concepts
Fundamentals
Asynchronous Programming: A programming model that allows multiple tasks to run concurrently without blocking the main thread. Key Benefit: Improves application responsiveness and performance, especially in I/O-bound operations. |
Concurrency vs. Parallelism:
|
Blocking vs. Non-Blocking:
|
Key Components
Promises/Futures |
Represent the eventual result of an asynchronous operation. Provide methods to handle success or failure. |
Callbacks |
Functions passed as arguments to be executed when an asynchronous operation completes. Can lead to ‘callback hell’ if not managed carefully. |
Async/Await |
Syntactic sugar built on top of Promises (in many languages) that makes asynchronous code look and behave more like synchronous code. |
