      6 description: The `name` property of Promise.all Resolve Element functions
      7 info: |
      8  A promise resolve function is an anonymous built-in function.
      9 
     10  17 ECMAScript Standard Built-in Objects:
     11    Every built-in function object, including constructors, has a `name`
     12    property whose value is a String. Functions that are identified as
     13    anonymous functions use the empty string as the value of the `name`
     14    property.
     15    Unless otherwise specified, the `name` property of a built-in function
     16    object has the attributes { [[Writable]]: *false*, [[Enumerable]]: *false*,
     17    [[Configurable]]: *true* }.
     18 includes: [propertyHelper.js]
