Function nest

Given a flat array of objects linked to one another, it will nest them recursively

Example

const comments = [
  { id: 1, comment_id: null },
  { id: 2, comment_id: 1 },
  { id: 3, comment_id: 1 },
  { id: 4, comment_id: 2 },
  { id: 5, comment_id: 4 }
];
nest(comments, "comment_id"); // [{ id: 1, comment_id: null, children: [...] }]
