gistfile1.txt

Read Carefully:

The Office of the Data Protection Commissioner(ODPCC) requires that personally identifiable information MUST be masked.
For example 

John Mutua should be presented as Jo** Mu***.
Dates should be masked as follows
2000-01-25
20**-0*-2*

Write a function in python and javascript that returns masked values in a dictionary/JSON object as below

first_name
last_name
date_of_birth
email

Example: Provided this prompt

    {
        first_name: "Greg",
        last_name: "Salama",
        date_of_birth: "1990-06-01",
        email: "[email protected]"
    }
Write a function that takes this as input and returns the following:

    {
        first_name: "Gr**",
        last_name: "Sa****",
        date_of_birth: "19**-0*-0*",
        email: "sa**********@*****.**m"
    }

Note: For emails and dates please note that the delimiters @ and - MUST remain in place

Use any Object oriented programming language between : Java, Python and Javascript: The last 2 are preferred.
