1. What is lazy loading in Angular? Why is it used?

In Angular, the by default tendency of NgModules is eagerly loaded. It means that as soon as the app loads, all the NgModules are loaded, whether or not they are immediately necessary. That's why lazy loading is required. Lazy loading is mandatory for large apps with lots of routes. This design pattern makes the app load NgModules when they are only required. Lazy loading helps keep initial bundle sizes smaller, which in turn helps decrease load times.
