How to pass keys as a list of strings to D3 group?

The d3.group documentation says:

d3.group(iterable, ...keys)

For example, if I have the following:

data = [
  {name: "jim",   amount: "34.0",   date: "11/12/2015"},
  {name: "carl",  amount: "120.11", date: "11/12/2015"},
  {name: "stacy", amount: "12.01",  date: "01/04/2016"},
  {name: "stacy", amount: "34.05",  date: "01/04/2016"}
]

But instead of:

d3.group(data, d => d.name, d => d.date)

I want to do something like:

d3.group(data, ['name', 'date'])

How should I do it? The reason is that I might not know the keys in advance and will have to do the grouping programatically.

Thank you!
