■ Examples: https://github.com/MarioCarrion/videos/tree/d5add59e12d3ee54797fcd1b592bb85a48ce1a3b/2022/03/17
== Installing
■ https://go.dev/dl/#go1.18
■ MacOS Homebrew: https://github.com/Homebrew/homebrew-core/pull/91369
■ goenv install: https://github.com/syndbg/goenv: run “goenv install 1.18.0”
■ “go install” https://twitter.com/golang/status/1503787326060875782
== New Feature: Type Parameters / Generics
Allows us to implement code that consists of data and behavior where types are not explicitly indicated, the simplest example would be defining a sorting algorithm where it can support any numeric type
■ https://go.dev/doc/faq#Type_Parameters
== New Feature: Fuzz Test Support
Another testing option that allows us to introduce inputs to our tests in order to find vulnerabilities or inputs that cause crashes
■ https://go.googlesource.com/proposal/+/master/design/draft-fuzzing.md
== Multi-Modules Workspaces
It’s a mode to allow working with multiple go modules at the same time
■ https://go.googlesource.com/proposal/+/master/design/45713-workspace.md
