DOMRectList
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The DOMRectList interface represents a collection of DOMRect objects, typically used to hold the rectangles associated with a particular element, like bounding boxes returned by methods such as getClientRects(). It provides access to each rectangle in the list via its index, along with a length property that indicates the total number of rectangles in the list.
Note:
DOMRectListexists for compatibility with legacy Web content and is not recommended to be used when creating new APIs.
