fmt.Println(string(res)) } We begin with the program’s main() function where the “MyString” string variable is initialized with the “hey, team!” value. Then, we declare the “res” slice of runes (Unicode characters) to store the modified string. We then initially set the “isText...

1. Declare Slice Variable and Make a Slice with X number of Elements The following example creates a slice with an initial size of 5. var distros []string distros = make([]string, 5) In the above: var – keyword distros – name of the slice variable ...
