Here, just a brief introduction to the personal understanding of the basics of object-oriented.

Class is a mold, instance is a mold carved out of something
Class is common, instance is based on the common character of the class to achieve something specific (object)
Instance was born from class.

The most common examples are:

Class: Bird

Method of Class (function): (bird) can fly

Properties of a Class (variable): Claws, Wings

Instance:

Object: Sparrow, a type of bird (Class)

Object Method (function): Sparrows can Fly

Object variable: Sparrow has 2 claws, a pair of wings
