Go Concurrent Tasks Explained with Examples

Running Concurrent Tasks

Go concurrent tasks use goroutines and channels for parallelism.

Understanding Goroutines

Goroutines are the cornerstone of concurrent programming in Go. They are functions or methods that run concurrently with other functions or methods. To create a goroutine, you simply prepend the go keyword to a function call. This launches the function in a new goroutine.

Using Channels for Communication

Channels in Go provide a way for goroutines to communicate with each other. They can be used to send and receive data between goroutines, ensuring synchronization. Channels are typed by the values they convey.

Buffered vs Unbuffered Channels

Channels can be buffered or unbuffered. Unbuffered channels block the sending goroutine until the receiver is ready, whereas buffered channels allow sending without blocking if there's space in the buffer.

Select Statement for Multiplexing

The select statement lets a goroutine wait on multiple communication operations. It's like a switch statement for channels, allowing you to handle multiple channel operations simultaneously.
