What would this JavaScript code snippet output if executed on Christmas Day (December 25th)?
const today = new Date();
const isChristmas = today.toString().includes("Dec 25");
console.log(isChristmas);

Does the answer depend on the system locale? Not all locales will have “Dec 25” in the string representation of date, right?

The correct answer is "undefined": the string representation of the date depends of the local culture.

The answer depends on the system locale! The other thing is that Christmas is culture dependent. In some countries it is on the 24th and not the 25th.

It will throw an error. If not now, it will in the future. It's js

Very nice question. Really couldn’t remember whether the month is abbreviated or not in the JS date format.

We have absolutely no idea. That’s probably the one area we haven’t explored. We can’t be in everything but I admire the field! Appears challenging and difficult. 😉

Isn't it possible for the answer to be false? Using the date constructor the timestamp will be set using UTC time which could be December 25th, but the toString method uses local time and could result in a date other than the 25th.

This question should have never been asked because it depends on timezones.

The correct answer is nobody knows since new Date can be mocked in the context and return a ⛇ emoji if you like.

False, all code throws errors before you look at it, only further proving Schrodinger's Law of Computer Code. It is the quantum cooooode

And what does it do in the majority of countries where Christmas isn't on the 25th?
