Difference between "router.navigate" and "router.navigateByUrl"

"router.navigate" and "router.navigateByUrl" are two methods used for programmatic navigation in Angular, but there is a subtle difference between them in terms of how they provide the URL for navigation.

router.navigate

The "router.navigate" method accepts an array of URL segments or an object that can contain multiple parameters. It is more flexible in terms of providing query parameters and fragments.

Example using an array of segments:

import { Router } from '@angular/router';

// ...

constructor(private router: Router) {}

// navigate to route '/details/123'
this.router.navigate(['/details', 123]);

Example using an object with query and fragment parameters:

import { Router } from '@angular/router';

// ...

constructor(private router: Router) {}

// Navigate to route '/details?id=123#section'
this.router.navigate(['/details'], { queryParams: { id: 123 }, fragment: 'section' });

router.navigateByUrl

The "router.navigateByUrl" method accepts a string containing the full URL you want to navigate to. This string should include the route, query parameters, and fragment if necessary.
Example:

import { Router } from '@angular/router';

// ...

constructor(private router: Router) {}

// Navigate to route '/details/123?id=123#section'
this.router.navigateByUrl('/details/123?id=123#section');

Choose between the two methods

Use "router.navigate" when you want to provide URL segments as separate elements, or when you need to handle query parameters and fragments within an object.

Use "router.navigateByUrl" when you have a complete URL string ready for navigation.

Both methods can be used effectively, and the choice between them will depend on how you prefer to provide URL details while navigating your Angular application.
