Eliminar detector de eventos dentro de un elemento

Revisa el código...

 document.querySelectorAll("button").forEach((element) => { element.addEventListener("keypress", respondToClick); function respondToClick() { console.log("Key Pressed"); console.log(element); } }); /* 'I don't know where to put...' // RemoveEventListener const removeEvent = () => { element.removeEventListener("click", respondToClick); }; */ // On HTML file <button onclick="removeEvent();" class="numbers">RemoveEventListener</button>;

¿Puedo agregar el botón removeEventListner que eliminará un eventListner dentro de un elemento?

Puede hacerlo de esta manera sin JS en línea (más información sobre por qué no hacerlo )

aquí hay más información sobre removeEventListener en MDN

 function respondToClick(event) { const element = event.target; console.log("Key Pressed:", event.key); console.log(element); } function removeEvent(event) { const element = event.target; element.removeEventListener("keypress", respondToClick) } document.querySelectorAll("button").forEach((element) => { element.addEventListener('keypress', respondToClick); element.onclick = removeEvent; });
 <button>removeEventListener</button>
