Builder Methods

Writing to Builder

Builder has several write methods:

var b strings.Builder
b.WriteString("Hello")  // append a string
b.WriteByte(' ')         // append a byte
b.WriteRune('世')        // append a rune
b.Write([]byte("!"))     // append bytes

result := b.String()     // "Hello 世!"

Use the method that matches your data type. WriteString is most common. Reset() clears the builder for reuse.
