Go - channel - basic
- Declare
- ch := make(chan int) // unbuffered, send will be blocked until receive was called
- ch := make(chan int, 0) // unbuffered, send will be blocked until receive was called
- ch := make(chan int, 3) // buffered, send will not be blocked until receive was called
- Channel is comparable
- Can send msg from one channel to another by method send
- Ex.send: ch <- x
- Ex. Receive: x <- ch
- Ex. Receive and discard result: <- ch
- Close a channel by method: close
- Ex. close(ch)
