Go was publicly announced in November 2009, and version 1.0 was released in March 2012.
Go has a backward compatibility promise for the major versions.
Why Go
- Compiles to a single native binary. Go includes the Go runtime into every binary, and it makes the distribution of Go programs easier. The drawback is that even for the smallest program Go produces a binary ~2MB.
Install Go
Follow instructions https://go.dev/doc/install.
Don’t forget to sudo both commands:
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.22.2.linux-amd64.tar.gzBecause initially I’ve made a newbie mistake by sudo’ing only the first, but not the second command.
Go code is grouped into packages, and packages are grouped into modules.

Idiomatic Go
- Comprehensibility over conciseness
A great rule of thumb for Go is accept interfaces, return structs.
