JS对象数组排列组合算法

const permutation = (source) => {  const arr = Object.keys(source);  const result = [];  const _result = {};  const convert = (arr, index) => {    for (let i = 0; i < arr[index].length; i++) {      if (source[arr[index]][i]) {        _result[arr[index]] = source[arr[index]][i]        if (index === arr.length - 1) {          result.push(JSON.parse(JSON.stringify(_result)));        } else {          convert(arr, index + 1);        }      }    }  };  convert(arr, 0);  return result;};// 测试permutation({  name: ['张三','李四','王二'],  age: [18, 16],  sex: ['男', '女']});

测试结果如下
