// assuming something we had a collection called movies and movies has two categories, action, comedy, 
// and comedy has three sections (kevin hart, mike epps, chris rock) and action has three sections (chuck norris, jet li, jackie chan). 

// if we were going to insert a document (movie) into the movies collection. 

let movieOne = { _id: "Jolade's movie log", path: null } // the path null marks this as a root node
const m = db.movies.insert(movieOne)

//to declare a node to the category 
const a = db.movies.insert({ path: `,${m._id},`, _id: "Jolade's movie log (action)" }) 
// adding the path declares it as a subdocument of the the initial movie log

// to insert a new node into the action category
const c = db.movies.insert({ path: `,${m._id},${a._id},`, _id: 'Chuck Norris' })

// to insert a leaf node into the chuck norris, sub_catetgory,

const leafMovie = db.movies.insert({ path: `,${m._id},${a._id},${c._id},` name: "Killer Cam by Chuck")
