In plain words: A Reusable Pagination Component in Lightning Web Components (LWC) is a standalone UI control that breaks down massive data lists into numbered pages. It calculates total pages dynamically based on record count, highlights the active page button, and communicates page changes to parent components using a standard JavaScript CustomEvent . Displaying hundreds of records at once on a Salesforce dashboard or custom table creates visual clutter and degrades browser rendering speeds. Rather than duplicating navigation buttons and page calculations across multiple custom components, creating a modular child pagination component ensures clean separation of concerns. The child component manages navigation state, while the parent handles data slicing and server-side queries.
