Learning Functional Programming in Go

The Go standard library 

The Go standard library is a set of core packages that enhance and extend the language.  By core, we mean that every time we compile our Go app, we'll get that pkg directory and it will be filled with the Go standard library packages. Go standard library packages have the following features:

• They add no extra overhead
• They are guaranteed to always exist
• They are guaranteed to always be backwards compatible (won't break between release cycles)

Using packages from Go's standard library will make our code easier to manage and more reliable. Example packages include the following:

• log
• fmt
• encoding/json
• database/sql/driver
• net/http
