1 - What is the difference between a route and a path?
A route is an abstract representation of a URL, while a path is a literal string that represents a URL.
2) What are the different types of routes in Angular?
There are three types of routes in Angular: absolute paths, relative paths, and queryParams.
3) How do you define a route in Angular?
You can define a route in Angular by using the `@RouteConfig` decorator.
4) What is the difference between a redirect and a forwardNavigation?
A redirect is used to change the current URL without reloading the page, while a forwardNavigation is used to load a new page.
5) How do you prevent a route from being accessed?
You can prevent a route from being accessed by using the `canActivate` guard.
6) How do you handle errors in Angular routing?
You can handle errors in Angular routing by using the `errorHandler` function.
7) What is the difference between the RouterModule and the RouterOutlet?
The RouterModule is used to configure the routing for your application, while the RouterOutlet is used to display the current view.
8) How do you lazy load a module in Angular routing?
You can lazy load a module in Angular routing by using the `loadChildren` property.
9) What is the difference between a route and a component?
A route is a URL path that is mapped to a component, while a component is the actual code that is displayed in the view.
10) How do you navigate to a route in Angular?
You can navigate to a route in Angular by using the `router.navigate()` method.
11 - What is the difference between a route parameter and a query parameter?
A route parameter is part of the URL path, while a query parameter is appended to the URL after a question mark.
12) How do you access route parameters in Angular?
You can access route parameters in Angular by using the `ActivatedRoute` service.
13) How do you pass data between routes in Angular?
You can pass data between routes in Angular by using the `queryParams` or `state` properties.
14) What is the difference between the `ActivatedRoute` and `Router` services?
The `ActivatedRoute` service provides information about the currently active route, while the `Router` service is used to navigate to different routes.
15) How do you test Angular routing?
You can test Angular routing by using the `RouterTestingModule` and the `ActivatedRouteStub`.
