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

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'?

首先定位「read this before commenting…」的滑鼠懸停彈出視窗，以及 https://javascript.info/try-catch 討論。檢查如何到達彈出視窗中的連結、如何描述 async/await，以及哪些 anchor 元素使用 name 而不是 id。完成的標準是彈出視窗中的連結仍然可用、async/await 的說明準確，且相關區段具有可用的 id。
