VS Code Instructions

Add "editor.fontLigatures": true to settings.json:

To open settings.json, from the File menu choose Preferences, Settings or use keyboard shortcut Ctrl+,. Then paste the following lines and save the file.

"editor.fontFamily": "Fira Code",
"editor.fontLigatures": true

If this doesn't work for you, you can try:

1. restarting VS Code;
2. wrapping the "Fira Code" section with additional apostrophes:

   "editor.fontFamily": "'Fira Code'",
   "editor.fontLigatures": true
