Exceeding String Bounds in Go

String indexes must stay inside the valid range.

For a string with length len(message), the first index is 0 and the last valid index is len(message) - 1.

message := "I love pancakes"

fmt.Println(string(message[len(message)-1])) // last character

Trying to access message[len(message)] goes past the end: the program panics with index out of range [15] with length 15.
