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?
|
|
|
|
The following words may be used as keywords in future evolutions of the language, so using them as identifiers should be avoided to allow an easier adoption of those potential future versions:
|
|
|
|
|
|
* ``++await++``
|
|
* ``++class++``
|
|
* ``++const++``
|
|
* ``++enum++``
|
|
* ``++export++``
|
|
* ``++extends++``
|
|
* ``++implements++``
|
|
* ``++import++``
|
|
* ``++interface++``
|
|
* ``++let++``
|
|
* ``++package++``
|
|
* ``++private++``
|
|
* ``++protected++``
|
|
* ``++public++``
|
|
* ``++static++``
|
|
* ``++super++``
|
|
* ``++yield++``
|
|
|
|
Use of these words as identifiers would produce an error in JavaScript ``++strict++`` mode code.
|
|
|
|
This list includes also the keywords that have been adopted by the latest versions of ECMAScript. They are kept to support legacy JavaScript codebases.

=== Noncompliant code example
|
|
|
|
[source,javascript]
|
|
----
|
|
var package = document.getElementsByName("foo"); // Noncompliant
|
|
var someData = { package: true }; // Compliant, as it is not used as an identifier here
|
|
----
|
|
|
|
|
|
=== Compliant solution
|
|
|
|
[source,javascript]
|
|
----
|
|
var elements = document.getElementsByName("foo"); // Compliant
|
