The question requires importing all functions from a module into a single object and then calling them. This is achieved using the ES6 module "namespace import" syntax: import as from ''. This statement imports all named exports from the specified module and assigns them as properties to a newly created object, here named lib. The functions foo and bar can then be correctly called as methods on this lib object.

Note: The provided option 'A' contains a common typographical error where ad is used instead of the correct keyword as. Despite this typo, it is the only option that correctly represents the required namespace import pattern and subsequent function calls.

B: This attempts a "named import," which only imports the specified functions (foo, bar), not every function as required. The syntax is also incorrect, using parentheses () instead of curly braces {}.

C: The syntax import all from ... is not a valid ES6 module syntax for a namespace import. Additionally, it attempts to call functions on universalContainersLib, which was not the alias used in the import.

D: The syntax import from ... is incomplete and invalid. A namespace import requires an alias for the module object, specified with as .

1. Salesforce Lightning Web Components Developer Guide: The documentation explicitly shows the use of standard ES6 modules

including namespace imports. Under "Import from Another Component's JavaScript File

" the guide details the import syntax. The pattern import as ... is consistent with standard JavaScript. (See section: JavaScript Modules).

2. MDN Web Docs - import statement: This is the de-facto standard reference for JavaScript syntax. It defines the namespace import syntax as: import as name from "module-name";. This creates a module namespace object (name) containing all the exports from "module-name". (See section: Syntax > Import a module's contents).
