(6 Questions)
- Q1. Throw some light on the new angular feature that doesn't use @NgModule
- Ans.
The new Angular feature that doesn't use @NgModule is called Ivy.
Ivy is the new rendering engine in Angular that doesn't rely on @NgModule for compilation.
It allows for faster compilation times and smaller bundle sizes.
Ivy enables features like improved tree shaking and better debugging capabilities.
Example: Angular 9 introduced Ivy as the default rendering engine.
- Q2. How would the application work without @NgModule
- Ans.
The application would not work properly without @NgModule as it is required to bootstrap the application and configure dependencies.
Without @NgModule, the application would not be able to bootstrap and start properly.
NgModule is used to configure dependencies, such as components, directives, and services.
NgModule also helps in organizing the application into modules for better maintainability and reusability.
- Q3. Mid level Angular interview questions

Component directives are custom directives that are components themselves (e.g. @Component)
- Q5. Can a service file have more than one instance? If yes how?
- Ans.
Yes, a service file can have more than one instance by creating multiple instances of the service class.

Each instance will have its own state and can be used independently.
This can be useful for scenarios where multiple instances of the same service are needed to handle different tasks.

- Ans.
Pipes in Angular are used for transforming data in templates.
Pipes are used to format data before displaying it in the view.
