d3.each() index doesn't begin at 0

My question is very similar to this. The solution there was that there was a <div> messing things up. There are no <divs> in mine.

I have this CoffeeScript code:

data = [0, 1, 2, 3, 4]
d3.select("body")
  .data(data)
  .enter()
  .each((d, i) =>
    console.log(i, d)
  )

With the desired console output being:

0 0
1 1
2 2
3 3
4 4

The actual console output is:

1 1
2 2
3 3
4 4

I can get the desired output with this code:

data = [0, 1, 2, 3, 4]
d3.select("body")
  .data(data)
  .each((d, i) =>
    console.log(i, d)
  ).enter()
   .each((d, i) =>
    console.log(i, d)
  )

But it just feels wrong to have two .each() calls.
