[JS] superEventHandler

이렇게쓰던것을

function handleMouseenter() {

  innerHTML = "The mouse is here!";

}

title.addEventListener("mouseenter", handleMouseenter);

요롷게 오브젝트를 묶어서 표현 (한번에 보기도쉽고 관리도쉬움)

const superEventHandler = {
MouseEnter: () => {
title.innerHTML = "The mouse is here!";
},

MouseLeave: () => {

~~

},

...
};


title.addEventListener("mouseenter", superEventHandler.MouseEnter);
