sure mate, just tell me the result of the following without trying it out.
If I remember correctly, 0 and 1 are considered falsy and truthy respectively, so it should be
falsy and truthy and falsewhich I believe would return false.Tried it out to double-check, and the type of the first in the sequence is what ultimately is returned. It would still function the same way if you used it in a conditional, due to truthy/falsy values.
yes, that is a solid logic, one that I also applied and expected to be the result.
that is until a Vue component started complaining that I am passing in a number for a prop that expects a boolean.
turns out the result of that code is actually: 0, because javascript
of course if you flip it and try
then you get false, because that’s what you really want in a language, where && behaves differently depending on what is on what side.
I was incorrect; the first part of my answer was my initial guess, in which I thought a boolean was returned; this is not explicitly the case. I checked and found what you were saying in the second part of my answer.
You could use strict equality operators in a conditional to verify types before the main condition, or use Typescript if that’s your thing. Types are cool and great and important for a lot of scenarios (used them both in Java and Python), but I rarely run into issues with the script-level stuff I make in JavaScript.
