Using querySelector on Node

I am doing something like:
const nodeList: NodeList = document.querySelectorAll(".foo");
const nodes = [...nodeList];
const result = nodes.map((n: Node) => n.querySelector("span"));
const nodeList: NodeList = document.querySelectorAll(".foo");
const nodes = [...nodeList];
const result = nodes.map((n: Node) => n.querySelector("span"));
The above will not work because querySelector is not from Node, but rather Element. Is there any good way to do this without manually tossing around Nodes?

Btw, my example is contrived, the real world use case is different. I really can't do it with just one querySelectorAll call in my case.

even though the returned type is NodeList, only elements can match a (non-pseudo-element) selector and I don't think querySelector(All) works with pseudo-element selectors

So I could just cast it?
