This script includes several key functionalities described earlier in the prompt while maintaining clean code practices and adhering to good coding standards like DRY (Don’t Repeat Yourself), KISS(Keep It Simple Stupid) principles etc.: 1-It fetches data from an API endpoint asynchronously using `fetch`.2.Renders customers’ information into a table dynamically including headers that are clickable for sorting purposes..3Has interactive elements such as buttons/checkboxes allowing CRUD operations directly within the HTML structure itself instead relying solely backend logic wherever possible thus reducing load times improving user experience overall due interactivity provided front end only 4Includes error handling mechanisms ensuring smooth functioning even under unexpected conditions like failed API calls etc ..5Utilizes modern ES6+ syntax making code more readable maintainable future-proof easier debugging testing..etc.
