Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
Destructuring is a convenient way of extracting multiple values from data stored in (possibly nested) objects and arrays. However, it is possible to create an empty pattern that has no effect. When empty curly braces or brackets are used to the right of a property name most of the time the intent was to use a default value instead.
|
|
|
|
|
|
This rule raises an issue when empty destructuring pattern is used.

=== Noncompliant code example
|
|
|
|
[source,javascript]
|
|
----
|
|
var {a: {}, b} = myObj; // Noncompliant
|
|
function foo({first: [], second}) { // Noncompliant
|
|
// ...
|
|
}

=== Compliant solution

|
var {a = {}, b} = myObj;
|
|
function foo({first = [], second}) {
