   const element = document.getElementById('myElement');
   const eventType = 'click';

Replace'myElement' with the appropriate ID or reference to the element from which you want to remove the event listener. Also, specify the correct event type you want to remove the listener for (e.g.,'click','keydown','mousemove', etc.). 2. Define the event listener function: If you have assigned a named function to the event listener, make sure to refer to it when removing the listener. Otherwise, if you used an anonymous function, you need to keep a reference to it for removal.

   function myEventListener(event) {
     // Event listener logic
   }

ReplacemyEventListener with the name of your event listener function, or assign your anonymous function to a variable. 3. Attach the event listener to the element: Attach the event listener using theaddEventListener() method.

   element.addEventListener(eventType, myEventListener);

ReplacemyEventListener with the appropriate function reference or variable if using an anonymous function. 4. Remove the event listener: To remove the event listener, call theremoveEventListener() method on the element with the same event type and listener function used during attachment.

   element.removeEventListener(eventType, myEventListener);

Again, replacemyEventListener with the correct function reference or variable. Note: If you used an anonymous function, make sure the reference used here is the same as the one used when adding the listener. By following these steps, you can remove an event listener in JavaScript. Ensure that you provide the correct element, event type, and listener function when usingremoveEventListener(). This will detach the specified listener from the element and prevent it from executing when the specified event occurs.
