Substrings

Extracting parts

Extract substrings using slice syntax:

s := "Hello, World!"
fmt.Println(s[0:5])   // "Hello"
fmt.Println(s[7:])    // "World!"
fmt.Println(s[:5])    // "Hello"

This works with byte indices. For ASCII strings, bytes and characters align. For Unicode strings, be careful not to slice in the middle of a multi-byte character.
