Simplified Coding's video: Kotlin Singleton Tutorial - Companion Object Operator Invoke

In this Kotlin Singleton Tutorial, we will learn how easy it is to use Singleton Pattern in Kotlin. (Compared to other languages such as Java). Singleton is an Object Oriented Design Pattern, and it is used when we want to have only a single instance of a class, that is shared throughout the application. It is often require, when the instance is frequently needed, so instead of creating the instance again and again, we can restrict it to just a single instance that will be shared throughout the application. Kotlin makes, singleton very easy with zero boilerplate code. We just need to use the keyword object and the Singleton class is ready.
