Introduction to Go
Simplicity, compilation, and Go's design goals.
Go (or Golang) was designed at Google for simplicity and speed: a small language, fast compilation, and a single static binary as output — no separate runtime to install on the target machine.
Every Go program starts in a `main` function inside `package main`. Variables can be declared explicitly (`var age int = 36`) or with shorthand type inference (`age := 36`).
Go has built-in support for concurrency via goroutines — lightweight functions that run independently, making it a common choice for networked services and backend infrastructure.
