Default zero values for all Go types
Variables declared without an initial value are set to their zero values:
0for all integer types,0.0for floating point numbers,falsefor booleans,""for strings,nilfor interfaces, slices, channels, maps, pointers and functions.
The elements of an array or struct will have its fields zeroed if no value is specified. This initialization is done recursively:
type T struct {
n int
f float64
next *T
}
fmt.Println([2]T{}) // [{0 0 <nil>} {0 0 <nil>}]Further reading
