':hover' popup with links, and no mention of async/await

[davidmaxwaterman]

1. hovering over 'read this before commenting…' displays a popup with some useful links, but moving the cursor to the popup to attempt to follow a link causes the popup to disappear...making the links useless. Well, it is possible if you carefully move the cursor over the little 'triangle' part of the popup...
2. the 'https://javascript.info/try-catch' discussion doesn't comment on its use with async/await, and it's a major use-case since it's the alternative of Promise's 'catch'. Also, this important_warn suggests try/catch isn't going to work with async/await, but that's isn't the case...
3. 'name' on anchor elements is deprecated (in favour of 'id'), and the document could use some more 'id's on other parts, like the above 'important_warn'?
