Go | 字符串拼接方式

go字符串的几种拼接方式：

1、fmt.Sprintf

s := fmt.Sprintf("%s%s%s", s1, s2, s3)

2、+运算符拼接

s := s1 + s2 + s3

3、strings.Join

s := strings.Join([]string{s1, s2, s3}, "")

4、strings.Builder
builder := strings.Builder{}
builder.WriteString(s1)
builder.WriteString(s2)
builder.WriteString(s3)
s := builder.String()

5、bytes.Buffer

buffer := bytes.Buffer{}
buffer.WriteString(s1)
buffer.WriteString(s2)
buffer.WriteString(s3)
s := buffer.String()
