why does db.collection.findOne() return less information than db.collection.find[1] in mongodb -

why db.collection.findone() return less information db.collection.find[1] in mongodb

i think return 1 document in mongodb, when run commands there info missing using findone method

you should use db.collection.find()[1]

if using db.collection.find (without parentheses) return what function doing

sample output db.collection.find (without parentheses).

function (query, fields, limit, skip, batchsize, options) {     var cursor = new dbquery(this._mongo, this._db, this, this._fullname, this._massageobject(query), fields, limit, skip, batchsize, options || this.getqueryoptions());     var connobj = this.getmongo();     var readprefmode = connobj.getreadprefmode();     if (readprefmode != null) {         cursor.readpref(readprefmode, connobj.getreadpreftagset());     }     return cursor; }
