The table below shows the full list of languages (and corresponding classes/aliases) supported by Highlight.js. Languages that list a Package below are 3rd party languages and are not bundled with the core library. You can find their repositories by following the links.
Note: The languages available will depend on how you've built or are included the library in your app. For example our default minified web build includes only ~40 popular languages.
