Hey everyone 
I’m currently learning Golang on KodeKloud and planning to take the Advanced Golang course next.
After finishing both, I want to master Go programming.
Can anyone (especially the KodeKloud team) please suggest the best book or resource to continue learning after these courses?
Thanks a lot!

There are a lot of wonderful resources on the web. One favorite of mine is this tutorial by Alex Edwards. You have to buy it, but I highly recommend it.

Or, you can’t go wrong with O’reilly’s Introducing Go
