Most developers that are familiar with dynamic scripting language like Ruby, JavaScript, or Python have been exposed to higher-order functions. Coming from a scripting background, it can be hard to translate that knowledge into Go, since the type system seems to get in the way. On the other hand, coming from a statically typed, primarily object-oriented language like C++, C#, or Java, the problem may be the opposite: static type systems are less of a stumbling block, but the usage of higher-order functions may be less intuitive. For programmers with functional experience, most of this knowledge may come across as very pedestrian, but hopefully this article will at least demonstrate how to use Go's type system with respect to functions.

In this article, we'll look at a few situations where function types in Go can be very useful. The reader is not assumed to be an experienced Go programmer, although a cursory knowledge of Go will certainly be helpful

Why I Like Go

I visited with PagerDuty yesterday for a little Friday beer and pizza. While there I got started talking about Go. I was asked by Alex, their CEO, why I liked it. Several other people have asked me the same question recently, so I figured it was worth posting.

Goroutines

The first 1/2 of Go's concurrency story. Lightweight, concurrent function execution. You can spawn tons of these if needed and the Go runtime multiplexes them onto the configured number of CPUs/Threads as needed. They start with a super small stack that can grow (and shrink) via dynamic allocation (and freeing). They are as simple as go f(x), where f() is a function.

set windowTitle to ""
tell application "System Events"
    set frontApp to first application process whose frontmost is true
    set frontAppName to name of frontApp
