How to configure VS Code for .sjs

[grtjn]

• Code > Preferences >Settings -> type: file extensions..
• Text Editor > Files should show up (at the top for me)
• The top says File Associations, and you can click edit settings.json there..
• and then you add this at the top of settings.json:

  "files.associations": {
    "*.sjs": "javascript"
  },
