== Why is this an issue?

include::../description.adoc[]

=== Exceptions

This rule ignores Immediately Invoked Function Expressions (IIFE), which are functions that are created and invoked without ever being assigned a name.

[source,javascript]
----
(function () { // Ignored by this rule

  function open() {  // Classic function declaration; not ignored
    // ...
  }

  function read() {
    // ...
  }

  function readlines() {
    // ...
  }
})();
----

This rule also ignores React Functional Components, which are JavaScript functions named with a capital letter and returning a React element (JSX syntax).


[source,javascript]
----
function Welcome() {
  const greeting = 'Hello, World!';

  // ...

  return (
    <div className="Welcome">
      <p>{greeting}</p>
    </div>
  );
}
