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?
|
|
|
|
Extra semicolons (``++;++``) are usually introduced by mistake, for example because:
|
|
|
|
* It was meant to be replaced by an actual statement, but this was forgotten.
|
|
* There was a typo which lead the semicolon to be doubled, i.e. ``++;;++``.
|
|
* There was a misunderstanding about where semicolons are required or useful.

=== Noncompliant code example
|
|
|
|
[source,javascript]
|
|
----
|
|
var x = 1;; // Noncompliant
|
|
|
|
function foo() {
|
|
}; // Noncompliant
|
|
----
|
|
|
|
=== Compliant solution
|
|
|
|
[source,javascript]
|
|
----
|
|
var x = 1;
|
|
|
|
function foo() {
|
|
}
|
|
----
|
|
|
|
=== Exceptions
|
|
|
|
This rule does not apply when the semicolon is after a line break and before ``++(++`` or ``++[++`` as it is often used in semicolon-less style.
|
|
|
|
[source,javascript]
|
|
----
|
|
var hello = 'Hello'
|
|
var world = 'World!'
|
|
var helloWorld = hello + ' ' + world
|
|
;[...helloWorld].forEach(c => console.log(c))
