How we can use typing effect anywhere of web page in drupal 8 or 9

Actually you can:
Anywhere you want, just add the syntax needed:
Here is a [rotate]simple|easy|cute[/rotate] way to rotate text

Could be on a page, could be on a view, anywhere.

Then, you will need to add the library and configuration to that specific page using hook_page_attachments():

function mymodule_page_attachments(array &$attachments) {
     // Check if the page if the one you need from the $request
     [...]
  
     // Attach the library.
     $attachments['#attached']['library'][] = 'text_rotator_filter/text_rotator_filter';
     // Add the configurations.
     $attachments['#attached']['drupalSettings']['text_rotator_filter'] => [
          'animation' => 'dissolve',
          'speed' => 350,
     ];
}
