Goroutines and Channels

could someone please give me a hint what I am doing wrong ... I think the first two questions should be alright, but I don't get the last one ... thank you ... Jan.

src/channels/read.go 
package channels

func readFromChannel() string {
channel := make(chan string)
go writeToChannel(channel)
readFromChannel() 
return
}

You're super close, you just need to return the channel result rather than calling the function recursively.

package channels

func readFromChannel() string {
  // CREATE A CHANNEL FOR string VALUES HERE
  c := make(chan string)
  // HERE, CALL writeToChannel AS A GOROUTINE, AND PASS IT YOUR CHANNEL
  go writeToChannel(c)
  // HERE, READ A STRING FROM YOUR CHANNEL AND RETURN IT
 return <- c
}
