Services is a type of category that surrounds by providing features that an app needs.
Service is simply a typescript class with a well defined purpose.
To increase modularity to your app, Angular distinguishes components from services
This is also known as separation of concerns.
A components primary job is to interact with template and nothing more.
A component mediates between the template and application logic by binding fields, properties and methods to our template.

These type of task can be handled by a separate class in our Angular. And that class is called Service
