Goroutines in Clojure

Goroutines
In this example, we’ll explore how to use goroutines, which are lightweight threads of execution. We’ll show a function execution both synchronously and asynchronously using goroutines.
Defining the Function: We define a function
f
that takes a string argumentfrom
and prints it along with a loop counteri
.Main Function: The
-main
function demonstrates different ways to call the functionf
.Synchronous call:
Asynchronous call using
go
macro from core.async to simulate goroutines:Anonymous function call via
go
macro:Sleep to ensure the main thread waits for the goroutines to finish:
Execution: To run the program, save the code in a file (e.g.,
goroutines.clj
) and execute it within a Clojure environment.
Example Output
When this program runs, you will see the output of the synchronous call first, followed by the mixed output of the goroutines, as they run concurrently.
This example illustrates how to use asynchronous execution in Clojure, leveraging core.async for functionality similar to goroutines.
