== Why is this an issue?

On the principle that clearer code is better code, you should explicitly `import` the things you want to use in a module. Using ``++import *++`` imports everything in the module and risks confusing maintainers. Similarly, ``++export * from "module";++`` imports and then re-exports everything in the module and risks confusing not just maintainers but also the module's users.

=== Code examples

==== Noncompliant code example

[source,javascript,diff-id=1,diff-type=noncompliant]
----
import * as Imported from "aModule";  // Noncompliant
----

==== Compliant solution

[source,javascript,diff-id=1,diff-type=compliant]
----
import {aType, aFunction} from "aModule";
----

\[~ann.campbell.2] Actually there is no problems with scopes or name conflicts when using wildcard in JS: all you have imported are properties of `Imported`. So I would just remove first sentence and keep the second one reworked a bit: "Listing the necessary imports makes clear what's wanted."
