var personObj = {
    name: 'John',
    lastname: 'Wick',
    age: 55,
    job: 'driver'
};

var validationResponse = validate(personObj, modelConfig);
console.log(validationResponse);
/* this should log:
{
    valid: false,
    neededKeys: [ 'phone' ],
    extraKeys: [ 'age', 'job' ],
    wrongTypeKeys: [],
    model: {
        name: 'John',
        lastname: 'Wick'
    }
