三个json数组之间的数据一一匹配组合

需求：

将以下三个json数组的数据一一匹配组合

["S","M","L"],["R","B"],["X","Y","Z"]

代码实现：

  Zuhe = (data) => {
    let heads = data[0];
    for (var i = 1, len = data.length; i < len; i++) {
      heads = this.addNewType(heads, data[i]);
    }
    return heads;
  }

  addNewType = (heads, choices) => {
    let result = [];
    for (var i = 0, len = heads.length; i < len; i++) {
      for (var j = 0, lenj = choices.length; j < lenj; j++) {
        result.push(heads[i] + ',' + choices[j]);
      }
    }
    return result;
  }

 //输出结果  
  printResult = (result) => {
    let List=[]
    for (var i = 0, len = result.length; i < len; i++) {
      List.push(result[i]);
    }

    console.log(List)
  }

  test = () => {
    this.printResult(this.Zuhe([["S", "M", "L"], ["R", "B"], ["X", "Y", "Z"]]));
  }


  componentDidMount() {
    this.test()
  }

结果
