[go-nuts] Re: converting slice of items into nested array

[Mikael Gustavsson]

There's no need to use maps, you want to follow this pattern:

for i := range items {
  if i==0 || !grouped(i-1, i) {
    appendToResult
  }
  appendToGroup
}

Here's the full example: https://play.golang.org/p/1e0rDDmq7b
