1. What do you understand by services in Angular?
In Angular, services are singleton objects that get instantiated only once during the lifetime of an application. An Angular service contains methods that are used to maintain the data throughout the life of an application. Angular services are used to organize as well as share business logic, models, or data and functions with various components of an Angular application.
Angular services offer some functions that can be invoked from an Angular component, such as a controller or directive.
