Average Age of date objects

[TuSKan]

Hello, In my problem I need to compute the average age of a sub population.

{  
    "peoples":[  
        {  
            "name":"Kelly Robertson",
            "birthDate":"1980-05-11 04:22:33"
        },
        {  
            "name":"Trevin Haley",
            "birthDate":"1985-09-12 12:03:10"
        }
    ]
}

It works for

avg(age(dateTime($.peoples.birthDate.*[1],'%Y-%m-%d %H:%M:%S')))

but not for all elements

avg(age(dateTime($.peoples.birthDate,'%Y-%m-%d %H:%M:%S')))

$.peoples.birthDate

is a list, so dateTime won't work. Maybe I should extend map() to accept parameters. I will think about it.

It could be this way ?

avg(age(map(dateTime, $.peoples.birthDate, args = '%Y-%m-%d %H:%M:%S')))

A map function could be very helpful. Could implement map as:

def map(f, array, args = None):
    return map(lambda x: f(x, args), array)
