Concurrent work with sync.Cond

Efficient coordination between different Goroutines is crucial to ensure smooth execution and resource management. Another powerful synchronization primitive provided by the Go standard library is sync.Cond (condition). The Cond type is associated with sync.Mutex and provides a way for Goroutines to wait for or signal the occurrence of a particular condition or changes in shared data.

Let’s explore how to use sync.Cond by creating a simple example of a work-in-progress (WIP) limited queue.

Exercise 18.12 – creating a WIP limited queue

Suppose you have a scenario where multiple Goroutines produce and consume items, but you want to limit the number of items in progress currently. sync.Cond can help achieve this synchronization. Here’s how to use it:

1. Create your folder and a main.go file, then write the following:

   package main
   import (
     "fmt"
     "sync"
     "time&quot...
