In those languages, objects are instances of a class and inherit properties and methods from that class. This is different from other object-oriented programming languages like Java or C#, which use classes to define objects and their properties and methods. When a property or method is accessed on an object, and that property or method is not defined on that object, JavaScript looks to the object’s prototype and continues the search up the prototype chain until it finds the property or method or reaches the end of the chain. In JavaScript, every object has a prototype, which is essentially a reference to another object that the current object inherits properties and methods from. Prototypes are a fundamental concept in JavaScript’s object-oriented programming model. Photo by Nangialai Stoman on Unsplash Understanding Prototypes
