JavaScript objects and instances

var person=new Object ();

var person2={};

Everything is an object.

The person is an instance of object, and it is a target.

The second person2 is the same, but it is generated in a literal way;

Instead of calling new Object () internally, it uses the Josn initialization method

The difference between an instance and an object, in terms of definition: the instance is already finished,

The object is a content structure with multiple attributes.

Instances are objects, and objects are not all instances.
There is no class (ES6) syntax in JS, so the concept of class is achieved by creating an object.
