What does the DOM property 'checked' indicate in a checkbox element?

1. It displays the default state

2. It shows if the checkbox is currently checked

3. It represents the initial value when the page loads

4. It indicates the total number of checkboxes

The 'checked' property of a checkbox element in the Document Object Model (DOM) is crucial for determining the current state of the checkbox at any given time. This property returns a Boolean value—true if the checkbox is selected (checked) and false if it is not. It is essential in forms and interactive applications, as it enables developers to understand if the user has interacted with the checkbox. Using the 'checked' property allows scripts to assess the current status of the checkbox, making it possible to implement conditional logic based on whether the checkbox is checked or not, enhancing the overall user experience. Since checkboxes can be toggled by user interaction, having a property that indicates their current checked state accurately reflects the user's choice at that moment. The other options refer to different aspects of checkboxes that do not directly relate to the current user interaction with the element. For instance, the default state is not indicative of the current condition after user interaction. The initial value upon page load may differ from the current state, and the total number of checkboxes does not correlate with the state of a single checkbox. Thus, the 'checked' property specifically provides real-time feedback on whether the checkbox is selected, making the assertion about it showing if the checkbox is currently
