How do async/await patterns work in different programming languages?

Async/await is a programming pattern that simplifies asynchronous code. In JavaScript, it allows you to write asynchronous code that looks synchronous. Other languages like Python and C# also implement similar patterns. Would you like to know how it works in a specific language?

Yes, can you explain it in Python?

In Python, async/await was introduced in version 3.5. You define an asynchronous function using the async def syntax and use await to call other asynchronous functions. This allows for non-blocking code execution, making it easier to handle I/O-bound tasks.

What about C#?

In C#, async/await was introduced in .NET Framework 4.5. You use the async keyword in method declarations and await to call asynchronous methods. This pattern helps to keep the UI responsive while performing long-running tasks.

Are there any drawbacks to using async/await?

Yes, while async/await simplifies code, it can lead to complexity in error handling and debugging. Additionally, improper use can result in performance issues, such as deadlocks.
