title: Is there a way in vscode to enable syntax highlighting without saving the file?
body: <p>Notepad++ has a Language menu which we can use to set the language of the current file without saving it, which provides syntax highlighting. This is useful for quickly checking out things, like, pasting an XML file and quickly analyzing it, typing out some JS code and copying it into a console.</p>
  
  <p>Is there a way to achieve this in vscode?</p>
