So I have an array of array of objects and wish to export that array to another array to use on future functions, but the problem is that on the for (for each array) the first run goes well but after the first run it adds the same content to the past run for example if I have 2 arrays with different content and execute the for function the first array is the same as the second array. 

Here is the code:

```
 var mark = [];
//defult 
var x_mark = { c_mark_desc_col:[], c_mark_col: null,  c_mark_col_image: null, 
            c_mark_action: "click", c_mark_origin:[0,0], c_mark_col_valor: false,
            c_mark_style: [null]
            //,c_cluster: cluster[0]         
};
    for (var i = 0; i < extras.marks.length; i++) {

        mark[i] = x_mark;
        if(!(extras.marks[i].mark_desc_col === "" || typeof extras.marks[i].mark_desc_col=== "undefined" || extras.marks[i].mark_desc_col=== null))
            mark[i].c_mark_desc_col = extras.marks[i].mark_desc_col;
        if(!(extras.marks[i].mark_col === "" || typeof extras.marks[i].mark_col=== "undefined" || extras.marks[i].mark_col=== null))
            mark[i].c_mark_col = extras.marks[i].mark_col;
        if(!(extras.marks[i].mark_col_image === "" || typeof extras.marks[i].mark_col_image=== "undefined" || extras.marks[i].mark_col_image=== null))
            mark[i].c_mark_col_image = extras.marks[i].mark_col_image;
        if(!(extras.marks[i].mark_action === "" || typeof extras.marks[i].mark_action=== "undefined" || extras.marks[i].mark_action=== null))
            mark[i].c_mark_action = extras.marks[i].mark_action;
        if(!(extras.marks[i].mark_origin === "" || typeof extras.marks[i].mark_origin=== "undefined" || extras.marks[i].mark_origin=== null))
            mark[i].c_mark_origin = extras.marks[i].mark_origin;
        if(!(extras.marks[i].mark_col_valor === "" || typeof extras.marks[i].mark_col_valor=== "undefined" || extras.marks[i].mark_col_valor=== null))
            mark[i].c_mark_col_valor = extras.marks[i].mark_col_valor;
        if(!(extras.marks[i].mark_style === "" || typeof extras.marks[i].mark_style=== "undefined" || extras.marks[i].mark_style=== null))
            mark[i].c_mark_style = extras.marks[i].mark_style;
    }
    alert("outside of 'for' posição 0 antes " + extras.marks[0].mark_col + "  depois " + mark[0].c_mark_col);
    alert("outside of 'for' posição 1 antes " +extras.marks[1].mark_col + "  depois " + mark[1].c_mark_col);
}

```
