# E0169: "global-groups" must be a boolean or an array

In a quick-lint-js configuration file, `"global-groups"` must be an array of strings, a boolean, or omitted. It is an error if `"global-groups"` is a boolean, a number, an object, a string, or `null`:

    {
        "global-groups": {
            "ecmascript": true,
            "browser": true
        }
    }

To fix this error, make `"global-groups"` an array:

    {
        "global-groups": [
            "ecmascript",
            "browser"
        ]
    }

Introduced in quick-lint-js version 0.4.0.
