self explanatory: From a few days ago, it has been bothering me with eslint errors for tsconfig. From what I have read tsconfig.json it's an exception to comments, since it's handle by the ts server own parser.
It's annoying me since.
You probably accidentally changed the language mode to "json". VS Code should automatically associate files named tsconfig.json
as "jsonc" (JSON with comments). Change the language mode back to "jsonc". You can click the language mode indicator in the status bar, or run Change Language Mode
in the command palette.
