Answer / Shiv Mohan Singh
The Singleton pattern is a design pattern that restricts the instantiation of a class to a single instance. In Angular, you can implement the Singleton pattern using the built-in services.nFor example, when you inject the $http service into your component or directive, it ensures only one instance of the $http service will be created and shared across all components and directives in your application.
