What is a Feature Module in Angular?
Answer
A Feature Module is a module that groups components, services, and routes related to a specific application feature. This organization improves maintainability by separating concerns and facilitates lazy loading. Each feature can evolve independently without affecting the rest of the application.
2What is the main advantage of lazy loading in Angular?
What is the main advantage of lazy loading in Angular?
Answer
