- channels are typed, thread-safe
- channels are queues
- channels allow different threads to talk to each other
- channels have buffer, it’s like the queue’s length
- if a channel’s buffer is 0, that means the queue’s length is 0
- the queue has to be read once there’s data sent to it, otherwise the sender will get blocked
creating a channel for sending integer data: ch := make(chan int)
sending data into the channel: ch <- 69
receiving data from the channel: v := <- ch
