Millised on += operaatori kasutamise eelised ja puudused stringide ühendamisel?

In Go, the += operator for strings is used for concatenation, that is, joining strings.

Advantages:

• Simplicity and readability of code.
• Convenient for a small number of concatenation operations.

Disadvantages:

• When used repeatedly in a loop, it leads to the creation of many intermediate strings, increasing garbage collector load and reducing performance.
• Strings in Go are immutable, so each += creates a new string.

For efficient concatenation of a large number of strings, it is recommended to use strings.Builder:

var builder strings.Builder
for _, s := range sliceOfStrings {
    builder.WriteString(s)
}
result := builder.String()

This reduces the number of allocations and improves performance.
