 8## JSONC
 9
10Zed also supports a super-set of JSON called JSONC, which allows single line comments (`//`) in JSON files.
11While editing these files you can use `cmd-/` (macOS) or `ctrl-/` (Linux) to toggle comments on the current line or selection.

13## JSONC Prettier Formatting
14
15If you use files with the `*.jsonc` extension when using `Format Document` or have `format_on_save` enabled, Zed invokes Prettier as the formatter. Prettier has an [outstanding issue](https://github.com/prettier/prettier/issues/15956) where it will add trailing commas to files with a `jsonc` extension. JSONC files which have a `.json` extension are unaffected.
16
17To workaround this behavior you can add the following to your `.prettierrc`
18
19```json
20{
21  "overrides": [
22    {
23      "files": ["*.jsonc"],
24      "options": {
25        "parser": "json",
26        "trailingComma": "none"
27      }
28    }
29  ]
30}
31```
