| 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> | |
