Question

So im trying to make objects that have prototype inheritance without the “new” operator using closures.
My code is:

var TABLE=function (tableId) {
var table=(document.getElementById(tableId)||{}),
    colName=[],
    rows,
    cols,
    selectedRow;

//private methods

    var updateRows=function(){
        //Code that updates the number of row of the table
    }
    updateRows();

//Declare the public methods for the object

var methods={
    prototype:{
        cols:function () {
        return cols;
        },
        rows:function () {
            return rows;
        }
    }
};
    return methods;
}

var table=Table("Inventory")
alert(table.rows()) //I get undefined
alert(table.prototype.rows()) //I get the actual number of rows

What am i doing wrong? Do you think i could use some better way of coding for this

I appreciate all the help.

We have to use the new keyword in case you want to use prototypical inheritance.

The best to use with example :-
