Convert javascript dot notation object to nested object

Question

I\'m trying to build a function that would expand an object like :

{
    \'ab.cd.e\' : \'foo\',
    \'ab.cd.f\' : \'bar\',
    \'ab.g\' : \'foo2\'
}
<

You need to convert each string key into object. Using following function you can get desire result.

 function convertIntoJSON(obj) {

                var o = {}, j, d;
                for (var m in obj) {
                    d = m.split(".");
                var startOfObj = o;
                for (j = 0; j < d.length  ; j += 1) {

                    if (j == d.length - 1) {
                        startOfObj[d[j]] = obj[m];
                    }
                    else {
                        startOfObj[d[j]] = startOfObj[d[j]] || {};
                        startOfObj = startOfObj[d[j]];
                    }
                }
            }
            return o;
        }

Now call this function

 var aa = {
                'ab.cd.e': 'foo',
                'ab.cd.f': 'bar',
                    'ab.g': 'foo2'
                };
   var desiredObj =  convertIntoJSON(aa);
