Which is the best book to learn GO language as a beginner?!
I recommend you this one
Donovan and Kernighan: anything from Kernighan is worth keeping on your shelf.
also softcover from https://www.chapters.indigo.ca/en-ca/books/the-go-programming-language/9780134190440-item.html?ikwid=the+go+programming+language&ikwsec=Home&ikwidx=0
(I’m in Canada)
For the record: The website of the book “The Go Programming Book”, which I highly recommend, is http://www.gopl.io/.
I second on that. The “The Go Programming Book” is worth of reading.
