i have a arrray of objects where i wish to convert the data from medicine to type string. The only problem is instead of returning the array of objects is returing me the array of medicine.

Example
input:

data = [{medicine: 1234, info: blabla},{medicine: 9585, info: blabla},..]

desired output:

data = [{medicine: 1234, info: blabla},{medicine: 9585, info: blabla},..]

What im getting?
Array of medicine numbers.

Here is my code:

var dataMedicines = _.map(data, 'medicine').map(function(x) {

                return typeof x == 'number' ? String(x) : x;

            });
