Using context instead of channel

Contexts can be implemented in functions executed in Go routines. Contexts are used instead of channel in the code for passing information between processes. The following code snippet shows the usage of context:

//main package has examples shown// in Go Data Structures and algorithms bookpackage main// importing errors,context,log and time packagesimport (  "errors"  "golang.org/x/net/context"  "log"  "time")// main methodfunc main() {  var delay time.Duration  delay = time.Millisecond  var cancel context.CancelFunc  var contex context.Context  contex, cancel = context.WithTimeout(context.Background(), delay)  go func(context.Context) {    <-contex.Done()    log.Printf("contex done")  }(contex)  _ = cancel time.Sleep(delay ...
