How to build a JSON object using collection of dot notation strings using JavaScript?

问题

I have a collection of strings in an array. These strings are the JSON paths that i select from a checkbox tree.

var selected = ['a', 'b.c.0.d', 'b.c.1.d', 'b.c.0.e', 'b.c.1.e'];

I want to save it to the database with the real data given by the user. So i want to create a JSON object like following structure. It can be further nested.

    { 
       "a":5,
       "b":{ 
          "c":[ 
             { 
                "d":5,
                "e":5
             },
             { 
                "d":5,
                "e":5
             }
          ]
       }
    }
