On one hand I've been using almost the exact statement 25 years ago in my Flash (ecmascript) tutorials to narrow down the point of operator precedence.

I still believe it's a good piece on your powerpoint if you want to teach. It's easy to fall, easy to grasp, and easy to unroll all the rules - that is, if the rules are actually set in stone.

On the other hand I've been through couple FAANG interviews, and twice I was presented with something similar and after I glanced at it for a half a minute the interviewer quickly proceed to "a ha!, you don't know! the interview is over , but I'm happy to tell you the right answer".

That part is not cool.
