hasOverflow.ts
const hasOverflow = (ele: HTMLElement) => ele.scrollHeight > ele.clientHeight || ele.scrollWidth > ele.clientWidth;The
`hasOverflow` function checks if an HTML element has overflow in its content. It does this by comparing the element's `scrollHeight` and `scrollWidth` properties to its `clientHeight` and `clientWidth` properties, respectively.If the scroll height or width is greater than the client height or width, it means there's overflow in the content. In this case, the function returns
`true`, indicating overflow. If there's no overflow, the function returns `false`.This function is useful when you want to check if an element needs scrolling. You can use it to determine whether a scroll bar should be displayed for an element based on whether it has overflow or not.
