Golang : invalid character ',' looking for beginning of value

In has been a while since I've encounter a strange error message that I couldn't comprehend. However, today is special since I've encountered this weird error message today while writing examples for Golang.

invalid character ',' looking for beginning of value

and the error was caused by a comma , at the end of each JSON data line

 var jsonDataStream = 
 {"Name":"Adam","Age":36,"Job":"CEO"},
 {"Name":"Eve","Age":34,"Job":"CFO"},
 {"Name":"Mike","Age":38,"Job":"COO"}

to get rid of this error, simply remove the , will do

 var jsonDataStream = 
 {"Name":"Adam","Age":36,"Job":"CEO"}
 {"Name":"Eve","Age":34,"Job":"CFO"}
 {"Name":"Mike","Age":38,"Job":"COO"}
