I have this array:

var myArray = [ 
    { familyName: 'one', subfamilies: 
        [ { subfamilyName: 'subOne', subItems: 
             [ { name: 'subOne', code: '1' }, 
               { name: 'subTwo', code: '2' } 
             ] } 
        ] 
     }, 
    { familyName: 'two', subfamilies: 
        [ { subfamilyName: 'subTwo', subItems: 
             [ { name: 'subOne', code: '1' }, 
               { name: 'subTwo', code: '2' },
               { name: 'subTwo', code: '3' }
             ] } 
        ] 
     } 
]

I need to divide that array in two diferent arrays with the same length if possible (my real array is so much longer), but I am having some problems getting it done. I create 2 blank array and, with for sentence read all the items. First I push the subItems in one blank array, but cannot get the way to create a new subFamily in a blank array variable and then push the sutItems array.

How can be this done?

Thanks a lot in advance.
