An Introduction To Go Lang
summary
Quick, practical tour of Go fundamentals with concrete code: how files and packages compile with go build and go mod, use of fmt for output and gofmt for formatting, zero value defaults for ints/floats/strings, pointers and nil, structs with methods and implicit interfaces by satisfaction, basics of testing with executable Example tests and go test. Shows channels and goroutines to build a pipelined processor, implements a finite state machine using channels (plus an exploration of generics) that is unit tested and runs, and covers slices vs arrays and append behavior.
