What method is used to check if an HTML attribute exists?

hasAttribute()
getAttribute()
checkAttribute()
existsAttribute()

The correct answer is: hasAttribute()

The method used to check if an HTML attribute exists is indeed hasAttribute(). This method is part of the Element interface in the DOM (Document Object Model) and allows you to determine whether a specified attribute is present on a given element. When you use hasAttribute() and pass the name of the attribute as an argument, it returns true if the attribute is found on the element, and false if it is not. This is particularly useful for conditionally performing actions based on whether certain attributes are set or not, thus enhancing your ability to interact dynamically with the DOM. In contrast, getAttribute() retrieves the value of an attribute if it exists, but it does not check for the presence of the attribute itself. checkAttribute() and existsAttribute() are not standard methods defined in the DOM, which is why they are not correct for this question.
