JavaScript Functions and Events Mocktest

You can attach multiple event listeners to the same HTML element in JavaScript without overwriting existing ones by using the addEventListener() method multiple times for the same event. Each call adds a new event listener, allowing developers to define multiple actions for the same event without replacing or overriding existing listeners.

The removeEventListener() method in JavaScript is used to detach or remove event listeners from HTML elements. It allows developers to unregister specific event handlers added using the addEventListener() method, effectively stopping those handlers from responding to subsequent events.
