Channels

Pick the line that creates a new UNBUFFERED channel of int. TypeScript doesn't have channels natively — closest analog is an EventEmitter or a stream. Go's channels are first-class language primitives with typed payload.

About this theme

Channels are typed pipes between goroutines. ch <- v sends, v := <-ch receives. Unbuffered channels are a synchronisation primitive: send blocks until receive completes. Buffered channels decouple the two. Channel direction (<-chan T, chan<- T) is part of the type signature.
