Is pseudocode allowed in *answers*?

There are several meta questions plus the help center making it clear that questions must provide real code.

However, it is unclear to me whether answers must therefore also be runnable code. Specifically, at one point I provided an answer where I used not-quite-syntactically-correct examples for brevity: as one comment pointed out, I neglected to provide correct async return types; additionally I chose not to include all the params from the original question code.

In my view the (pseudo)code in the answer is intended to better illustrate the algorithmic suggestions I was making, to which end the specifics and even being directly runnable were less of a concern than readability. However, the commenter disagreed, and I can't find a meta question directly addressing this.

Must answers only contain real, runnable code (like questions) or is (pseudo/partial)code okay in answers when accompanying textual explanations?
