Same as in question:
- Go or Golang - what is the correct name of this language?
Go is the correct name.
I found note on wikipedia:
The language is often referred to as Golang because of its domain name,
golang.org, but the proper name is Go.
Also on golang.org I found:
Is the language called Go or Golang?
The language is called Go. The "golang" moniker arose because the web site is golang.org, not go.org, which was not available to us. Many use the golang name, though, and it is handy as a label. For instance, the Twitter tag for the language is "#golang". The language's name is just plain Go, regardless.
A side note: Although the official logo has two capital letters, the language name is written Go, not GO.
