goroutines-async-channel-send-receive-waiting example

Sending data to a goroutine via an async channel. Both SEND and RCV will block/wait for data.

These are my 5 main example of using goroutines,

• goroutines-async-channel-receive-no-waiting
• goroutines-async-channel-send-receive-waiting <- You are here
• goroutines-multi-core
• goroutines-waitgroup
• goroutines-worker-pools

CHANNELS (MESSAGE PASSING)

Giving a channel msgCh,

Send,

msgCh <- "Jeff"                             // WAITS/BLOCKS

Receive,

say = <-msgCh                               // ALSO WAITS/BLOCKS

RUN

go run goroutines-async-channel-send-receive-waiting.go

Simply press return to exit.

Output is always,

Sent message Jeff
                             0 Received message Jeff
Sent message Clif
                             1 Received message Clif
Sent message Jack
                             2 Received message Jack
Sent message Jill
                             3 Received message Jill

Try slowing down or speeding up the SEND or RCV and you will always get the same result because both sides block/wait.
