  1. TIL: 1. Spreading an object in JavaScript e.g. {...thing} does not include properties from the object's prototype, and 2. There's a situation where I care that spreading an object doesn't include properties from the prototype. I was more surprised by #2 than #1.

      The situation where I cared was that I was trying to "clone" a React event, with one property modified. By spreading the event into a new one, I was effectively removing almost all the properties of the event (because most of them were on the prototype).

        This totally feels like the kind of "trivia" that one would be grilled on in a bust-em style technical interview. Will I ever forget it? No. Will it ever come in useful again in my life? Probably also no. And I guess that's how bust-em technical interview questions are born.
