With modern JavaScript you can easily cast a NodeList to an Array, e.g. `let spansArray = [...element.querySelectorAll("span")]`.
I find both `element.nextElementSibling` and `element.next()` to be examples of poor API design. The former one is more verbose than needed while the latter one is so short you can't even tell whether it's a method or a property.

Ah, thanks. I got bitten by this recently and didn't know what to do with this "thing that's not an array but seems like it should be, and doesn't always behave like one"
Before that ES2015 allowed you to do Array.from(nodeList, mapFunc?) which I still use due to the optional mapping function e.g. Array.from(document.querySelectorAll('a'), a => a.href)
