Posted at

問題点

以下のようなコードがあるとき、onKeyUp内のe.target.selectionStartのみ型エラーが生じる

 <MainTextarea
        text={text}
        onChange={e => {
          setText(e.target.value);
          setSelectionStart(e.target.selectionStart);
        }}
        onFocus={e => {
          setSelectionStart(e.target.selectionStart);
        }}
        onKeyUp={e => {
          setSelectionStart(e.target.selectionStart);
        }}
      />
