Answer:
A. DOM
Read Explanation:
Document Object Model (DOM)
- The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure.
- Each node in the tree represents a part of the document, such as an element, attribute, or text content.
- Key Characteristics:
- Tree Representation: The document is organized hierarchically, starting with the root element (usually <html>).
- Dynamic Updates: It allows programs (primarily JavaScript) to dynamically access, modify, add, or delete document content, structure, and style in real-time without reloading the page.
- Event Handling: The DOM supports event-driven programming, enabling interactivity based on user inputs like clicks, keyboard presses, or mouse movements.
- Standards: The DOM is standardized by the W3C (World Wide Web Consortium) to ensure consistency across different web browsers.
- Core API Methods: Developers often use methods like getElementById(), querySelector(), and createElement() to manipulate the DOM tree efficiently during runtime.
