Go Concurrency
The key component of the Go concurrency model is the goroutine, which is the minimum executable entity in Go. Everything in Go is executed as a goroutine, either transparently or consciously. Each executable Go program has at least one goroutine, which is used for running the main() function of the main package. Each goroutine is executed on a single OS thread according to the instructions of the Go scheduler, which is responsible for the execution of goroutines. The OS scheduler does not dictate how many threads the Go runtime is going to create because the Go runtime will spawn enough threads to ensure that GOMAXPROCS threads are available to run Go code.
However, goroutines cannot directly communicate with each other. Data sharing in Go is implemented using either channels or shared memory. Channels act as the glue that connects multiple goroutines. Remember that although goroutines can process data and execute commands, they cannot communicate directly...
