In populate() function of service.js, I was trying to build an object array to store the passengers' name, house, placemark and marker. Basically, I created a global array, say database[], then when iterating through every passenger's information in PASSENGERS[],I add both the property and value dynamically:

    database[i].name = PASSENGERS[i].name;
    database[i].house = PASSENGERS[i].house;
    database[i].placemark = placemark;
    database[i].marker = marker;

When I validate the code using 'Inspect Elements' on Google, it pops out the message: Uncaught TypeError:Cannot set property 'name' of undefined.

Is that the correct way to declare an object array? Or is there anything wrong with adding new property and values? Much appreciated.
