Le Stum says the strength of Go include its built-in tooling, quick compile times and deploys, and easy troubleshooting, as well as the way it makes code easy to understand. "In Python, you could write super-elegant list comprehensions and beautiful code that's almost mathematical. But if you didn't write the code, then that elegance can come at the expense of readability," he explains, noting that in enterprise software, engineers spend more time reading code than writing it.

Go is good for Scripting:

You can make go source code executable like this:

///usr/bin/env go run "$0" "$@" ; exit "$?"

package main

func main() {
    println("Hello world!")
}

Then I can just chmod a+x hello.go and execute ./hello.go. More options at https://gist.github.com/posener/73ffd326d88483df6b1cb66e8ed1e0bd

Unix pipes are awesome. Go scripts can use them like one of these:

This is an interesting way to package multiple scripts into one directory: https://github.com/jpignata/toolbox
