Thank you for making this video. It was very helpful. However, can you kindly help me understand what the piece of code below?

var mongoose = require('mongoose');
var bcrypt = require('bcrypt');



var db = mongoose.connection;

// User Schema
var UserSchema = mongoose.Schema({
//Schema detail
});

var User = module.exports = mongoose.model('User', UserSchema);

module.exports.createUser = function(newUser, callback) {
bcrypt.hash(newUser.password, 10, function(err, hash){
if(err) throw err;
// Set hashed pw
newUser.password = hash;
// Create User
newUser.save(callback)
});
}

I don't quite get what this line - "var User = module.exports = mongoose.model('User', UserSchema);", is try to do. Is it User needed somewhere else? Why cannot it be just "var User = mongoose.model('User', UserSchema);"


Thank you so much if you can help.
