Q
Which JavaScript method is used to prevent the default behavior of an element's action?

Answer & Solution

Answer: Option Option B
Solution:
The preventDefault() method is used to prevent the default behavior of an element's action in JavaScript. This method is commonly used with event listeners to prevent the default actions of elements such as links, buttons, or form submissions. By calling event.preventDefault() within an event handler, you can stop the default action from occurring, allowing you to implement custom behaviors or actions based on user interactions. The addEventListener(), onclick(), and removeEventListener() methods are used for event handling, but preventDefault() specifically prevents default behaviors.
