Reduce problem

Someone that has a clean solution for this?
I have this data structure:

 posts: Post[]
 
interface Post {
  stream : {
    id: string
    name: string
  }
  isCompleted: boolean
  // other data...
}

 posts: Post[]
 
interface Post {
  stream : {
    id: string
    name: string
  }
  isCompleted: boolean
  // other data...
}

I want to get a response with two data structures (maps) mapped by stream name that separates completed streams and uncompleted streams where the keys are the stream names.
A stream is considered completed if all the posts in that stream are completed.
I guess a reduce would be the way to go but would need help with some specifics.

completedStreams: {
 // keys are the names of the completed streams and inside is an array with     // the posts
}
uncompletedStreams: {
 // keys are the names of the unCompleted streams and inside is an array with   // the posts for these streams
}

completedStreams: {
 // keys are the names of the completed streams and inside is an array with     // the posts
}
uncompletedStreams: {
 // keys are the names of the unCompleted streams and inside is an array with   // the posts for these streams
}
