What operations are performed when concatenating string data?

In Go, string concatenation is usually performed using the + operator or the strings.Join function.

• The + operator simply concatenates two or more strings:

s := "Hello, " + "world!"
fmt.Println(s) // Hello, world!

• The strings.Join function is used to join a slice of strings with a specified separator:

import "strings"

words := []string{"Go", "is", "awesome"}
result := strings.Join(words, " ")
fmt.Println(result) // Go is awesome

When strings are concatenated, a new string is created containing the sequence of characters from the original strings. It is important to remember that strings in Go are immutable, so each concatenation creates a new string in memory.
