如何在函数中动态写入逗号字符(作为参数)？

function dynamicComma() {
  var param1 = "value1";
  var param2 = "value2";
  var comma = ",";
  var result = param1 + comma + param2;
  console.log(result);
}

dynamicComma(); // 输出：value1,value2

def dynamic_comma():
    params = ["value1", "value2"]
    comma = ","
    result = comma.join(params)
    print(result)

dynamic_comma()  # 输出：value1,value2

public static void dynamicComma(String... params) {
    String result = String.join(",", params);
    System.out.println(result);
}

dynamicComma("value1", "value2"); // 输出：value1,value2
