Go supports only 25 keywords. It’s very simple, which has the advantage of a low learning curve. I’ve never posting it while using Go. Let me summarize the meaning of each keyword today.

break     default      func    interface  select
case      defer        go      map        struct
chan      else         goto    package    switch
const     fallthrough  if      range      type
continue  for          import  return     var
