the right ways

1. normal return object

const getUser = user => {return { name: user.name, age: user.age };};

const user = { name: "xgqfrms", age: 21 };

console.log(getUser(user));
//  {name: "xgqfrms", age: 21}

2. (js expressions )

const getUser = user => ({ name: user.name, age: user.age });

const user = { name: "xgqfrms", age: 21 };

console.log(getUser(user));
//  {name: "xgqfrms", age: 21}
