Create schema on mongoose whether to use 'new' keyword or not?

I understand what is the use of Schema and model in mongoose, however when defining/creating a new Schema there are 2 ways of doing it (that I found of), and I'm confused by it,

1st way (without new - no instance created):

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/dbName');

// No 'new' keyword
var mySchema = mongoose.Schema({
    parameter1 : String,
    parameter2 : String
});

var modelName = mongoose.model('collectionName', mySchema);

and 2nd way of doing it (with new - an instance created):

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/dbName');

// There is 'new' keyword
var mySchema = new mongoose.Schema({
    parameter1 : String,
    parameter2 : String
});

var modelName = mongoose.model('collectionName', mySchema);

What's the differences between the two? when to use one or the other?

Both way are fine, but according to code standard and mongoose library, we use 2nd way. It's follow extending & Implementation feature like OOP.

Schema & Model we use in nodejs for validation & restrict unwanted object & fields inserting into mongo collection.

Thats the reason for uses.
