What is Haskell's async library and how do I use it?

Can you explain what the Haskell async library is?

The Haskell async library provides a way to perform concurrent programming, allowing you to run multiple tasks simultaneously.

How do I install the async library in my Haskell project?

You can install the async library by adding it to your project's cabal file or using Stack with the command: cabal install async.

Can you give me an example of using async in Haskell?

Sure! Here's a simple example:

import Control.Concurrent.Async

main :: IO ()
main = do
    result <- async (someLongRunningTask)
    -- Do other work here
    wait result

What are some common use cases for the async library?

Common use cases include web scraping, parallel computations, and handling multiple I/O operations without blocking.
