Implements Base36 encoding and decoding, which is useful to represent large integers in a case-insensitive alphanumeric way.
import "github.com/martinlindhe/base36"
fmt.Println(base36.Encode(5481594952936519619))
// Output: 15N9Z8L3AU4EB
fmt.Println(base36.Decode("15N9Z8L3AU4EB"))
// Output: 5481594952936519619
fmt.Println(base36.EncodeBytes([]byte{1, 2, 3, 4}))
// Output: A2F44
fmt.Println(base36.DecodeToBytes("A2F44"))
// Output: [1 2 3 4]
For basic base 36 conversion, you can use strconv.FormatUint() from the stdlib.
