- What is the Document Object Model (DOM) and how does it represent an HTML document?
- How can JavaScript be used to add, remove, or modify elements in the DOM? Provide examples of methods used for these operations.
- Explain the difference between the innerHTML and textContent properties. When should each be used?
- What are events in the context of the DOM, and how can they be used to interact with users? Discuss the concept of event bubbling and capturing.
- Discuss the performance implications of frequent DOM manipulations. What are some best practices to minimize reflows and repaints?
- How can modern JavaScript libraries and frameworks (like React, Angular, or Vue) help manage DOM manipulations? Compare their approaches with vanilla JavaScript.

2.avaScript interacts with the DOM to add, remove, or modify elements using methods like document.createElement() to create elements, element.removeChild() to remove elements, and element.setAttribute() to change attributes. For example, document.body.appendChild(newElement) adds a new element to the body, and element.remove() directly removes an element from the DOM.
