`record` should be `customerRecord` or `customer`?

In fact, the same concern could apply to `record` being present before `onCustomer(..)` is specified to receive it.

'record' refers to the parameters in function onCustomer(customer), so will it be better to use word 'customer'?

customerPromise.then( function onCustomer(customer){
    ordersPromise.then( function onOrders(orders){
        customer.orders = orders;
    } );
} );
