How can you directly access a DOM property in JavaScript?

1. By using the getAttribute() method

2. By accessing it as a property of the element object

3. By calling a function to retrieve it

4. By using querySelector() with the property name

The correct answer is: By accessing it as a property of the element object

Directly accessing a DOM property in JavaScript is accomplished by treating the DOM element like a JavaScript object. Each element retrieved from the DOM—such as through queries with methods like `document.getElementById()` or `document.querySelector()`—can be interacted with by accessing its properties directly, just like you would with any JavaScript object. For example, if you want to retrieve the value of an input element, you can access it directly by using the property name, such as `element.value`. This method is straightforward and efficient, allowing developers to manipulate or read properties of DOM elements directly without additional overhead. The other options do involve interacting with the DOM, but they do not provide a direct way to access properties in the manner described. The `getAttribute()` method is used to retrieve attribute values but does not access properties; calling a function to retrieve it introduces unnecessary complexity, and using `querySelector()` primarily targets elements but does not inherently retrieve properties by name. Therefore, accessing properties as part of the element object is the simplest and most effective method in this context.
