Linting错误：将此数组“sort”操作移动到单独的语句中

Question

你可以帮助修复下面的javascript函数的linting错误。

错误：将此数组“排序”操作移动到单独的语句。

  item.EmployeeDetails = item.EmployeeDetails
                            .sort((a: IEmployeeDetails, b: IEmployeeDetails) => {
        if (a.employeeType < b.employeeType) {
            return 1;
        }
        if (a.employeeType > b.employeeType) {
            return -1;
        }
        return 0;
    });

Answer 1

const empDetail = Object.assign(item, {});

 return empDetail['EmployeeDetails '].sort( (a: any , b: any) => {
    if (a.employeeType < b.employeeType) {
      return 1;
    }
    if (a.employeeType > b.employeeType) {
      return -1;
    }
    return 0;
  });

}

Answer 2

sort（）改变了数组。见https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/prototype#Mutator_methods

所以，尝试省略赋值运算符：

item.EmployeeDetails.sort((a: IEmployeeDetails, b: IEmployeeDetails) => {
    if (a.employeeType < b.employeeType) {
        return 1;
    }
    if (a.employeeType > b.employeeType) {
        return -1;
    }
    return 0;
});
