Kuidas tõhusamalt ja turvalisemalt sisestada elemente stringi ajal tsüklit?

In Go, it is recommended to use the strings.Builder type for efficient and safe insertion of elements into a string during a loop. It allows accumulating strings without creating many intermediate objects, significantly improving performance and reducing garbage collector load.

Usage example:

var builder strings.Builder
for _, elem := range elements {
    builder.WriteString(elem)
    builder.WriteString(",") // for example, add a separator
}
result := builder.String()

Using concatenation with += in a loop is inefficient, as each operation creates a new string. strings.Builder works with an internal buffer that expands as needed, which is safe and fast.
