Structs

type Person struct { Name string; Age int }
p := Person{Name:"Sam", Age:30}
fmt.Println(p.Name)
  • Custom types: Structs group fields for clarity; they are the foundation of most Go models.
  • Initialization: Use literal syntax to set fields; zero values are safe defaults.
  • Export rules: Field names starting with uppercase are exported to other packages.
