== Why is this an issue?

By convention, a file that exports only one class, function, or constant should be named for that class, function or constant. Anything else may confuse maintainers.

=== Noncompliant code example

[source,javascript]
----
// file path: myclass.js  -- Noncompliant
class MyClass {
  // ...
}
export default MyClass;
----

=== Compliant solution

[source,javascript]
----
// file path: MyClass.js
class MyClass {
  // ...
}
export default MyClass;
----

=== Exceptions

Case, dots ( ``++.++`` ), underscores ( ``++_++`` ) and dashes  (``++-++``) are ignored from the name comparison. Postfixes in filenames like ``++.dev++`` in ``++my.class.dev.js++`` are also ignored.
