The ToTitle() function is an inbuilt function of the bytes package which is used to get a copy of the byte slice (s – treated as UTF-8-encoded bytes) with all the Unicode letters mapped to their title case.

It accepts one parameter (s []byte) and returns a copy with all the Unicode letters mapped to their title case.

Syntax:

func ToTitle(s []byte) []byte

Parameter(s):

• s : The byte slice to be used to create a copy of the title case byte slice.

Return Value:

The return type of the bytes.ToTitle() function is a []byte, it returns a copy with all the Unicode letters mapped to their title case.

Example 1:

// Golang program to demonstrate the
// example of bytes.ToTitle() function

package main

import (
	"bytes"
	"fmt"
)

func main() {
	fmt.Printf("%s\n",
		bytes.ToTitle([]byte("Every moment is a fresh beginning.")))
	fmt.Printf("%s\n",
		bytes.ToTitle([]byte("merhaba dünya, nasılsın?")))
	fmt.Printf("%s\n",
		bytes.ToTitle([]byte("Be so good they can't ignore you.")))
}

Output:

EVERY MOMENT IS A FRESH BEGINNING.
MERHABA DÜNYA, NASILSIN?

Example 2:

// Golang program to demonstrate the
// example of bytes.ToTitle() function

package main

import (
	"bytes"
	"fmt"
)

func main() {
	var str []byte
	var result []byte

	str = []byte("Every moment is a fresh beginning.")
	result = bytes.ToTitle(str)
	fmt.Printf("Original string: %s\n", str)
	fmt.Printf("Title case string: %s\n", result)
	fmt.Println()

	str = []byte("merhaba dünya, nasılsın?")
	result = bytes.ToTitle(str)
	fmt.Printf("Original string: %s\n", str)
	fmt.Printf("Title case string: %s\n", result)
	fmt.Println()

	str = []byte("Be so good they can't ignore you.")
	result = bytes.ToTitle(str)
	fmt.Printf("Original string: %s\n", str)
	fmt.Printf("Title case string: %s\n", result)
}
