Another reason why people might struggle to get Syntax Highlighting working is because they don t have the appropriate syntax package installed  While some default syntax packages come pre-installed  like Swift  C  JS  CSS   others may not be available   To solve this you can Cmd   Shift   P    install Extensions  and look for the language you want to add  say  Scala      Find the suitable Syntax package  install it and reload  This will pick up the correct syntax for your files with the predefined extension  i e   scala in this case   On top of that you might want VS Code to treat all files with certain custom extensions as your preferred language of choice  Let s say you want to highlight all   es files as JavaScript  then just open  User Settings   Cmd   Shift   P    User Settings   and configure your custom files association like so      files associations            es    javascript

Note that for  quot Untitled quot  editor   quot Untitled-1 quot    quot Untitled-2 quot    you now can set the language in the settings  The previous setting was   quot files associations quot              quot untitled-  quot    quot javascript quot      This will not always work anymore  because with VSCode 1 42  Q1 2020  will change the title of those untitled editors  The title will now be the first line of the document for the editor title  along the generic name as part of the description  It won t start anymore with  quot untitled- quot  See  quot Untitled editor improvements quot  Regarding the associated language for those  quot Untitled quot  editors   By default  untitled files do not have a specific language mode configured  VS Code has a setting  files defaultLanguage  to configure a default language for untitled files  With this release  the setting can take a new value  activeEditorLanguage  that will dynamically use the language mode of the currently active editor instead of a fixed default  In addition  when you copy and paste text into an untitled editor  VS Code will now automatically change the language mode of the untitled editor if the text was copied from a VS Code editor    And see workbench editor untitled labelFormat in VSCode 1 43
