How to Safely Convert a Byte Array to a String in Go?

Converting a Byte Array to a String in Go

The provided code attempts to transform a byte array into a string. However, using the naive approach of str = string(bytes[:]) is not recommended. Instead, consider implementing the following steps:

Define a function that converts a byte slice to a string, as shown below:

func convert(b []byte) string {
    s := make([]string, len(b))
    for i := range b {
        s[i] = strconv.Itoa(int(b[i]))
    }
    return strings.Join(s, ",")
}

This function achieves the desired conversion by iterating through the byte array, converting each byte to an integer string using strconv.Itoa, and joining the resulting strings with commas.

To utilize this function, simply pass the byte slice as an argument:

bytes := [4]byte{1, 2, 3, 4}
str := convert(bytes[:])

This will populate the str variable with the converted string "1,2,3,4".
