Design Patterns: Singleton

Learn everything there is to know about the Singleton Design Pattern

The Singleton Design Pattern is one of the most commonly used Design Patterns in software engineering. It is a core pillar of many applications, and understanding it is a requirement for any developer because it ensures that a class has only one instance and provides a global point of access to that instance. This is particularly useful for managing resources efficiently, maintaining consistency across the application, and synchronizing access in multithreaded environments. In this course, Amichai Mantinband will teach you everything you need to know to understand why we need the singleton pattern and how to use it effectively in our applications.
