Well    Title    Ramones   is an array of strings  But    01   Title    02    Ramones    is an array of object   If you are willing to push properties or value into one object  you need to access that object and then push data into that  Example  nietos indexNumber  yourProperty yourValue  in real application   nietos 0  02    Ramones    If your array of object is already empty  make sure it has at least one object  or that object in which you are going to push data to   Let s say  our array is myArray    so this is now empty array  the JS engine does not know what type of data does it have  not string  not object  not number nothing  So  we are going to push an object  maybe empty object  into that array  myArray push      or myArray push         This will push an empty object into myArray which will have an index number 0  so your exact object is now myArray 0   Then push property and value into that like this   myArray 0  property   value    in your case  myArray 0   01      value

The below solution is more straight-forward  All you have to do is define one simple function that can  CREATE  the object from the two given items  Then simply apply this function to TWO arrays having elements for which you want to create object and save in resultArray    var arr1     01   02   03    var arr2     item-1   item-2   item-3    resultArray           for  var j 0  j lt arr1 length  j              resultArray j    new makeArray arr1 j   arr2 j          function makeArray first second        this first   first      this second   second
