My most idiosyncratic JS opinion is that we should all write `0, { x } = y;` instead of `({ x } = y);` so you don't have to jump to the end of the line to add the parenthesis. If only I could convince tooling to support this... (i.e. get prettier not to add the parentheses back)

Several people blamed the recent npm incidents on JS's minimal standard library. I think that's wrong: the affected packages are mostly either already covered by node or could not reasonably be in a standard library. But! I'm always taking suggestions for new stdlib features.
