Purpose:

The purpose of this blog post is to provide a comprehensive guide to understanding and implementing modals in LWC. By the end of this article, you'll have a solid understanding of how to create and customize modals to suit your specific requirements within the Lightning Web Components framework.

example.js

import { LightningElement } from 'lwc';
  
  export default class Example extends LightningElement {
      isShowModal = false;
      openModal() {
          this.isShowModal = true;
      }
      closeModal() {
          this.isShowModal = false;
      }
  }

One common use case for custom modals in LWC is implementing a confirmation dialog for critical actions such as deleting a record. By encapsulating the confirmation logic within a modal component, developers can ensure a consistent user experience across the application. For instance, when a user attempts to delete a record, a custom modal can prompt them to confirm the action, preventing accidental deletions and providing clarity on the consequences of their decision. This not only enhances the application's usability but also reinforces data integrity and user trust.
