I was wondering what techniques patterns are you using to share variables between promises. E.g.

fetchAuthor()
  .then(response => {

    const authorId = response.id

    return fetchLatestIssues(authorId)
  })
  .then(response => {

    const issueId = response.id

    // I need the authorId here
   return fetchCommentsByAuthorOnIssue(authorId, issueId)
 })
