Javascript将对象名称提取到数组中

Question

如何在JavaScript中获取数组的对象名？

{
    "Ford F-150": [
        {
            "year": 2007,
            "model": "Ford F-150"
        },
        {
            "year": 2007,
            "model": "Ford F-150"
        },
        {
            "year": 2007,
            "model": "Ford F-150"
        }
    ],
    "Toyota Camry": [
        {
            "year": 2011,
            "model": "Toyota Camry"
        }
    ],
    "Dodge RAM": [
        {
            "year": 2005,
            "model": "Dodge RAM"
        }
    ]
}

我希望结果如

var result = ["Ford F-150", "Toyota Camry", "Dodge RAM"]
