Get deeper understanding what is prototype, Object.setPrototypeOf and obj.__proto__ and ways of use it in JavaScript. - javascript prototype
Before of all let’s consider what an object is in JavaScript:In ECMAScript, reference types are structures used to group data and functionality together and are often incorrectly called classes. Reference types are also sometimes called object definitions because they describe the properties and methods that objects should have.const person=new Object; person.name='Olga'; person.age=26 person.sayName=function { console.
Also, you can define custom constructors that have properties and methods for your type of object. The previous example can be rewritten using the constructor pattern next way: function Animal { this.name=name; this.speed=speed; this.getSpeedInfo=getSpeedInfo; } function getSpeedInfo { console.log; } const turtle=new Animal; const rabbit=new Animal; console.log; //true
