The unevaluatedItems lesson needs work

[jdesrosiers]

The unevaluatedItems lesson is a lesson for items, not unevaluatedItems. While you can use unevaluatedItems in place of items and get the same result, this lesson does nothing to show an actual use case for the keyword. Notice that this passes the lesson.

{
  "type": "object",
  "properties": {
    "name": {
      "type": "string"
    },
    "age": {
      "type": "integer"
    },
    "skills": {
      "type": "array",
      "prefixItems": [
        { "enum": ["HTML", "CSS", "JavaScript"] },
        { "enum": ["HTML", "CSS", "JavaScript"] },
        { "enum": ["HTML", "CSS", "JavaScript"] }
      ],
      "items": { "type": "string" }
    }
  }
}

A lesson on unevaluatedItems should include extending and/or closing a tuple using an applicator of some kind. Here's an example of adding an item to the tuple and closing it to further extension.

{
  "$ref": "#/$defs/tuple",
  "prefixItems": [true, true, { "type": "number" }],
  "unevaluatedItems": false,

  "$defs": {
    "tuple": {
      "type": "array",
      "prefixItems": [
        "type": "string",
        "type": "boolean"
      ]
    }
  }
}
