You can remove an event listener in Ember.js by using the removeEventListener method.


Here is an example of how you can remove an event listener in Ember.js:

import Ember from 'ember';

export default Ember.Component.extend({
  didInsertElement() {
    this._super(...arguments);
    
    // Add event listener
    this.element.addEventListener('click', this.handleClick);
  },
  
  willDestroyElement() {
    this._super(...arguments);
    
    // Remove event listener
    this.element.removeEventListener('click', this.handleClick);
  },
  
  handleClick(event) {
    console.log('Clicked!');
  }
});


In this example, we are adding a click event listener to the component's element in the didInsertElement hook. We are also removing the event listener in the willDestroyElement hook to clean up when the component is destroyed.
