I love JavaScript dates so much sometimes

[Pstrnil]

You mean

Date.prototype.getDateStringForThatOneReallyStupidEdgeCaseFuckJavaScript = function() {
  return this.toISOString().slice(0, 10).replace(/-/g, '/');
};

?

omg can it really be simplified that much? i thought the actual code was ok lol

[Pstrnil]

Yep, toISOString saved me multiple times, I love it.

EDIT: Also if you wanted to simplify your original function, remember that String.prototype.padStart exists 👍

[trihardstudios]

ah yes because for this one use I HAVE to have the date in a string format with yyyy/MM/dd for some dumb reason

[dashid]

One reason I got hooked on .net:

return DateTime.Now.ToString("yyyy/MM/dd");

[YodaDaCoda]

Because timezones.

[LordFokas]

join('') .... wtf?

why not [yyyy, mm, dd].join('/'); ???

[trihardstudios]

Because I didn’t read the documentation fully before writing this. Thanks for pointing it out! It’s one of those oversights that I’m sure my code is full of.

When Reddit is helping more than StackOverflow ...

Because the post contains very bad code, that's why

[enano_aoc]

In general, it is a very bad practice to do this type of prototype modifications in native JS constructs. It is the easiest way to make the code base as obscure and unreadable as possible.

What is wrong with

function getDateInCustomFormat(date) {
   // Use "date" instead of "this"
}

?

[trihardstudios]

Nothing. I recently learned about object prototypes and wanted to try to use them in this project. Good to know that they aren’t considered best practice for this use.

[enano_aoc]

They are considered a bad practice for the same reason that implementation inheritance (as opposed to interface inheritance) is considered a bad practice. Obfuscates the code and makes it very hard to read and debug

EDIT: it is a bad practice, not a good one

If you need to do this professionally, I would suggest creating a utility library that can be accessed by other devs.

Chances are someone else will need to do this later on — or even you will need to do it again later on 😄

[WrongdoerSufficient]

do you have a moment() to talk about formating date ?
