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"

FYI the reason it's not an array is because if you store a reference to it, it will stay up to date as and when the DOM changes.

The NodeList returned by querySelectorAll() is not live. There is really no reason for it to return a NodeList other than backward compatibility.

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)
