Building massive parser with Go Routines

Well, this is the first article of this space. I'm learning Golang in the last weeks, and comparisons with another languages are inevitable. I decided to write this article from a need I had in my job. I need to create a simple application where need to import 15K items from Rest API, each page with 12 items. Testing with C# (Console Terminal) using Paralels the minimum time operation was 1 minute. Using Go with Go Routines the average down to 0.5 miliseconds, awesome! Below you can see how I do that.
