The simple, easy, and safest way is to assign a string to bytes array is,

[]byte("String_Value")

Consider the below example,

// Go language program to assign string
// to bytes array

package main

import (
	"fmt"
)

// Main function
func main() {
	// Declare a byte array
	var b []byte

	// Assigning the string to bytes array
	b = []byte("Hello, world!")

	// Printing the type and value
	// of bytes array
	fmt.Printf("%T, %v\n", b, b)

	// Appending the string at the end of
	// the bytes array
	b = append(b, []byte("Okay!")...)
	fmt.Printf("%T, %v\n", b, b)
}

Output:

[]uint8, [72 101 108 108 111 44 32 119 111 114 108 100 33]
[]uint8, [72 101 108 108 111 44 32 119 111 114 108 100 33 79 107 97 121 33]
