And the author probably would not know what is going on too six months or more after it was written. ---

Here you have one of those operator precedence things that, unless you know, you don’t really know. In a code review, I would suggest adding parens to make it clear the result of the whole expression is being spread. The other bit is the behavior of object spread on non-spreadable values (not just falsey). I guess here you either know or don’t. But it’s a little confusing in the object spread case because unlike array spread, object spread won’t error when attempting to spread an non-spreadable value. Array spread, on the other hand, requires iterables to spread (object spread accepts any value with own properties). Note: `document.all` is a falsy value that _will_ spread, but thats just because `document.all` is a monstrosity. ---

So the bigger question is, is there any code that :sen: @senocular doesn’t understand? 😜 ---

And `obj` isn’t a great middle ground between concision and clarity.
