listLanguages() returns a list of supported languages. It does not return language aliases. highlight.js has extensive support of language aliases which can be viewed here https://highlightjs.readthedocs.io/en/latest/css-classes-reference.html#language-names-and-aliases But because of using listLanguages(), TW does not take advantage of alias. getLanguage() method on the other hand supports aliases. https://highlightjs.readthedocs.io/en/latest/api.html#getlanguage-name To summarize, now user can use javascript, js or jsx for the code block. getLanguage() will return an object which means highlight.js supports this language.
