Master promise chaining in TypeScript by sequencing tasks with resolve and reject, using setTimeout and then to manage sequential results and a final console print.

Master async/await and promises through error handling, chaining, and data fetching, including return data types, set timeouts, and basic debugging with console logs.

Enhance the ABM contact application by updating render logic for edit and delete actions and wiring edit and delete buttons to modify contacts in place.

Implement delete contact functionality in a TypeScript app by wiring a delete function to UI actions, filtering by contact id, and handling callbacks to remove the contact and related data.

Implement an edit contact feature by locating a contact using its ID from a context array, populating name and email inputs, and updating or saving changes via the edit button.

Learn how to manage contacts by adding and updating entries with a contact model, using update functions, and importing and exporting data via a textbox list.

Update contact from the user interface by reading common name and common email input values via document.getElementById, then save or update, delete, and refresh data to SQL local storage.

Learn how to use local storage to store and retrieve data, stringify and parse JSON, handle null and default, and read content via export function for a UI.
