Full Stack JavaScript Techdegree Graduate 16,080 PointsThere was an error with your code: TypeError: 'undefined' is not an object (evaluating 'event.target.className = "spin"'
Am i supposed to add a specific thing to the parameter in the event listener?, thanks for the help
const btn1 = document.getElementById("button1");
const btn2 = document.getElementById("button2");
const btn3 = document.getElementById("button3");
function spinElement(event) {
//Applies spinning animation to button element
event.target.className = "spin";
}
btn1.addEventListener('click', spinElement())
btn2.addEventListener('click', spinElement())
btn3.addEventListener('click', spinElement())

btn1.addEventListener('click', spinElement()) // bad
btn1.addEventListener('click', spinElement) // good
