This article will explain in detail how to achieve combinatorial inheritance 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. Combinatorial inheritance integrates prototype chain and embezzlement constructor, and centralizes the advantages of both. Methods can be defined on prototypes for reuse, and each instance can have its own properties.

2. The parent constructor is called twice in the process.

Once the child constructor uses the parent constructor called by apply/call, and the other is the parent constructor called when the parent class instance is assigned to the prototype object of the child class when the child class uses prototype inheritance

Example

Function A (name,age,sex) {this.name = name; this.age = age; this.sex = sex; this.arrs = [1pr 2je 3]}; A.prototype.sayName = function () {return this.name} function B (name,age,sex) {A.apply (this,arguments)} B.prototype = new A () Object.defineProperty (B.prototype, "constructor", {enumerable:false, value:B}) let C1 = new B; let C2 = new B ('C2WH 18pr female'); console.log (C1.sayName ()); / / "C1" C1.arrs.push (4); console.log (C1.ageMatic C1.sextile C1.arrs); / 18LetterMale, console.log (C2.sayName ()) / / "C2" console.log (C2.agegradeC2.sexgradeC2.arrs); / 18recoveryfemaleinheritance, [1mem2jin3] this article on "how to achieve combinatorial inheritance in JavaScript" ends here.
