  There is an array that is passed to the function as an argument:
  

  let city = [
          {c: 'Nashville', state: 'TN', latitudes: 36.17, longitudes: -86.78},
          {c: 'New York', state: 'NY', latitudes: 40.71, longitudes: -74.00},
          {c: 'Atlanta', state: 'GA', latitudes:33.75, longitudes: -84.39},
          {c: 'Denver', state: 'CO', latitudes: 39.74, longitudes: -104.98},
          {c: 'Seattle', state: 'WA', latitudes: 47.61, longitudes: -122.33},
          {c: 'Los Angeles', state: 'CA', latitudes: 34.05, longitudes: -118.24},
          {c: 'Memphis', state: 'TN', latitudes: 35.15, longitudes: -90.05},
      ];

  
  
  how to make 4 arrays in this function, which will contain:
  first array: all values ​​with;
  second array: all state values;
  third array: all latitudes;
  fourth array: all longitudes values;

  const xxx = arr =>
  
    arr.reduce((acc, n) => (
  
      Object
  
        .entries(n)
  
        .forEach(([ k, v ]) => (acc[k] ||= []).push(v)),
  
      acc
  
    ), {});
