const Data = { "a": { "name": "Steve", "car": ["lamborghini", "nissan"] }, "b": { "name": "Alex", // "car": ["cadillac", "dodge"] }
};
const DataSearch = (item, searchString) => Object.keys(Data).map(id => { if (Data[id][item].indexOf(searchString) >= 0) return id;
}).filter(v => v);
console.log(playerDataSearch("car", "lamborghini"));
