What is the benefit of typing newly created DOM elements in TypeScript?

When appending a new element to the DOM, why should you use the correct type in TypeScript?

Work with the DOM using TypeScript to write safer, clearer, and more predictable front-end code. Apply precise types to elements, events, and form inputs to avoid runtime errors and improve interactivity. Use type-driven patterns to select, update, create, and remove DOM elements with confidence.

Understand how TypeScript interprets DOM elements and why precise typing matters for interactive applications. Learn essential techniques such as type assertions, type guards, and null safety to prevent common DOM-related errors.

Use TypeScript to write safer event-driven code by typing events, handlers, and event targets correctly. Extend these skills to create reliable form validation logic with strongly typed inputs and predictable data handling.

Work with advanced DOM APIs through a type-safe lens. Use generic selectors, update element properties safely, and create or remove DOM nodes with consistent TypeScript patterns that reduce bugs and improve maintainability.
