JSON output

Now let's say that we have the Citi Bike station data in our stationData struct value and we want to save that data out to a file. We can do this with json.marshal:

// Marshal the data.outputData, err := json.Marshal(sd)if err != nil {    log.Fatal(err)}// Save the marshalled data to a file.if err := ioutil.WriteFile("citibike.json", outputData, 0644); err != nil {    log.Fatal(err)}
