What is ViewModel implementation in software development?

ViewModel implementation is a design pattern used in software development, particularly in MVVM architecture, to separate the UI from the business logic.

Can you explain how it works with an example?

Sure! In an MVVM application, the ViewModel acts as a bridge between the View and the Model. For instance, in a weather app, the ViewModel fetches weather data from the Model and prepares it for display in the View.

What are the benefits of using ViewModel?

The benefits include improved separation of concerns, easier unit testing, and better management of UI-related data.

Are there any common pitfalls to avoid?

Yes, common pitfalls include overloading the ViewModel with too much logic and not properly managing the lifecycle of data.
