色々　メモ


input HTMLInputElement = <HTMLInputElement>
inputに

const samplae: NodeListOf<Element> = app!.querySelectorAll("");
listに

interface HTMLElementEvent<T extends HTMLElement> extends Event {
    path: T;//ジェネリック
}
addEventListener('click', (e: HTMLElementEvent<HTMLInputElement>) => {});
addEventListener時にも

const target = items_arr.filter((item) => { return item; });
