The interface of each object is a class, a template that indicates functions and values are accessible to any instance. Initially, developers intended this communication ability for sending messages for network communication or asynchronous IO. It was later popularized as simple functions invoked on ...

What is an object? Inobject-oriented programming (OOP), objects are the things you think about first in designing a program and they are also the units of code that are eventually derived from the process. In between, each object is made into a genericclassof object, and even more generic...

To solve problems, OOP developers design class hierarchies, focus on proper encapsulation, and think in terms of class contracts. The behavior and state of object types are paramount, and language features, such as classes, interfaces, inheritance, and polymorphism, are provided to address these ...
class Human (firstName, lastName) { constructor (firstName, lastName) { /* ... */ } sayHello () { console.log(`Hello, I'm ${this.firstName}`) } } It’s easier to declare multiple methods on Classes compared to Constructors. You don’t need the Object.assign syntax. You just ...
