+Add multiple event listeners with the same handler to an element.
+
+- Use `Array.prototype.forEach()` and `EventTarget.addEventListener()` to add multiple event listeners with an assigned callback function to an element.
+
+```js
+const addMultipleListeners = (el, types, listener, options, useCapture) => {
+  types.forEach(type => el.addEventListener(type, listener, options, useCapture));
+}
+```
+
+```js
+addMultipleListeners(
+  document.querySelector('.my-element'),
+  ['click', 'mousedown'],
+  () => { console.log('hello!') }
+);
+```
