Chapter 11: Channels – An Advanced Concurrency Pattern

The term channel indicates a medium or a path that allows you to transfer information or data from one end to the other. In the context of concurrency, channels allow us to share data by establishing a communication channel between the concurrent tasks. These concurrent tasks are often termed coroutines, which share the data by communicating through the channels. Channels are advanced concurrency patterns in V that solve the problem of explicitly handling data synchronization techniques among coroutines.

We can communicate between the coroutines with the help of shared objects. In V, these can be structs, arrays, or maps. But the problem with this approach is that you need to take explicit care of concurrency synchronization techniques such as protecting the shared objects using locks such as the read-only rlock or the read/write lock to prevent data races, as we learned in the Sharing data between the main thread and...
