Due to historical reasons, the code is in subfolder "1". With SVN removal, we place the code back and remove the annoying "1" folder.

JavaScript mode supports several configuration options:
|
|
<ul>
|
|
<li><code>json</code> which will set the mode to expect JSON
|
|
data rather than a JavaScript program.</li>
|
|
<li><code>jsonld</code> which will set the mode to expect
|
|
<a href="http://json-ld.org">JSON-LD</a> linked data rather
|
|
than a JavaScript program (<a href="json-ld.html">demo</a>).</li>
|
|
<li><code>typescript</code> which will activate additional
|
|
syntax highlighting and some other things for TypeScript code
|
|
(<a href="typescript.html">demo</a>).</li>
|
|
<li><code>statementIndent</code> which (given a number) will
|
|
determine the amount of indentation to use for statements
|
|
continued on a new line.</li>
|
|
<li><code>wordCharacters</code>, a regexp that indicates which
|
|
characters should be considered part of an identifier.
|
|
Defaults to <code>/[\w$]/</code>, which does not handle
|
|
non-ASCII identifiers. Can be set to something more elaborate
|
|
to improve Unicode support.</li>
|
|
</ul>
|
|
</p>
|
|
|
|
<p><strong>MIME types defined:</strong> <code>text/javascript</code>, <code>application/json</code>, <code>application/ld+json</code>, <code>text/typescript</code>, <code>application/typescript</code>.</p>
