You could count the objects and use it for one of the three types to return.

function getType(array) {
    var count = array.reduce(function (r, a) {
        return r + (typeof a === 'object');
    }, 0);
    
    return count === array.length
        ? 'array of objects'
        : count
            ? 'mix values'
            : 'normal';
}

console.log([
    ['a', 'b', 'c'],
    [{ id: 1 }, { id: 2 }],
    [{ id: 1 }, { id: 2 }, 'a', 'b']
].map(getType));
