This article will explain in detail how to create classes in JavaScript. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

1. Define a prototype object, and then create an object that inherits it with Object.create ().

2. Use the constructor to define its prototype property, and the prototype property that calls the constructor-constructor will be used as the prototype of the new object.

The class syntax of ES6 is actually the syntax sugar that builds the function prototype.

Example

Fuction Engineer (para1,para2) {this.para1 = para1;this.para2 = para2;...} my Bill = new Engineer ("Bill", "24")

This method requires new () to create an instance.
