Singleton Pattern in Javascript

In this article, you will learn how to implement a singleton pattern in Javascript.


Understanding Singletons?


A Singleton is a design pattern that limits the instantiation of a class to a single instance.

It ensures that only one instance of a class can be created throughout the system.


Declaring singletons example


  1. let application = new class{  
  2.   constructor(name){  
  3.     this.name = name;  
  4.   }  
  5.   start(){  
  6.     console.log(`This is ${this.name}`);  
  7.   }  
  8. }('Start');  
  9.   
  10. application.start();
