javascript - 将多个参数传递给 Promise 函数？

Question

通常，您需要将“另一个”参数以及“结果”传递给链式函数。如何做到这一点？

这是一个 Parse 云代码示例:

var _ = require('underscore');
Parse.Cloud.define("doSomething", function(request, response)
    {
    var companyId = request.params.company;
    blah...

    companyFromCompanyId(companyId).then(function(company)
        {
        blah...
        return employeesFromCompany(company, kount);

    }).then(function(employees)
        {
        blah...
        // here, we would like to have passed in 'company' as an argument
        // as well as the "employees" result:
        ...  company.get("name") ...
        blah...
        }
        ,
        function(error) {blah...}
        );
});

因此，通过 then(function(employees) 我希望有“更多参数”进来。

(显然，可以在更大的范围内创建一个变量。在这个问题中，我问如何将更多参数传递给 .then)

根据@BenjaminGruenbaum 的评论进行更新

    Parse.Cloud.define("doSomething", function(request, response) {
        var companyId = request.params.company;
        blah...

        companyFromCompanyId(companyId)
          .then(function(company) {
             return [employeesFromCompany(company, kount), company];
           })
          .spread(function(employees, company)
            {
              blah... // employees
              var theCompanyName = company.get("name");
              blah...
            })
          .catch(function(error) {blah...});
    });
