JavaScript always know my truest of desires

Programming Javascript is roughly the equivalent of hitting your head with a hammer or trying to uninstall McAfee.

As if Javascript wasn’t complex enough, let’s introduce TypeScript and Coffescript and then write transpilers so we can convert said languages back into Javascript, which we could have done in the first place.

And all the new versions of all the above constantly being released. I'm so glad I don't use those languages anymore.

These languages only exist because JS is so dumb in the first place

Use stringly-typed everything, and always padStart your numbers.
Saves running into issues with numbers outside the 52-bit integer range.
And padding start means you don't have to worry about pesky sort functions.

Just don't do maths. Simple.

Maybe you could do a manual sort.
Provide a "captcha" prompt, and ask which comes first in the list... You know, to make sure the user is a human! And you get free sorting.

I mean, this strangely is a compelling idea...

I always try to prove myself human with wrong answers. Typically the first screen is an AI training screen, then the next screen is one the computer knows but wants to see if you know. By answering the first one wrong and the second correct, I'm hoping to poison the data.

Iirc they require 5 votes with the same response. Your effort won't do anything, other than flag you as unreliable.

Afaik 4chan (of course) did that poisoning correctly, "classifying" the unknown words as "penis" (of course).

I'm happy enough being classed as unreliable, either way they don't get good training data.

That's a good rule for life in general, really.

Note if you put the image link in the url bar of the post rather than the body it lets people see it while scrolling (url + title can be edited so you can edit it to do that still if you want)

thanks!

using 3rd party client (and first "image post" I've made on this platform) and wasn't sure how image post should be made.

I couldn't believe it, tried it out, what the actual heck? I mean I get all these weird string vs number comparison but sorting actual numbers and this comes out? What kind of drugs were the designers of javascript (or at least this function) on... Who thought it was a good idea to sort numbers lexicographically??

Iirc Array.sort requires you to pass a function in, or it casts into strings and sort them.

Is there even any case where you would want this?

Well, 3 out of 5 correct ain't bad. With some more trial runs we might get this thing nailed!

So, I think just yesterday or the day before someone on here was saying we shouldn't make fun of JavaScript anymore.

JavaScript: You chose this path, now I have a surprise for you

Deploying surprise in 3, 2... Hold up for a seco d that wasn suppossed to happen.

Ugh, I just ran into this in Terraform. Why is this a thing?

It's just sorted alphabetically (technically it is the UTF16 code order). To be fair it's a sane default for most use cases. In JS case you can define a very simple callback to change the behavior to numeric sorting (a,b => a<b). Many other sorters provide a flag instead, but numeric sorting is seldom the default as it is not as useful most of the time in weakly typed languages.

weakly typed languages

Well, looks like we found the problem right there

I don't think JS works that way

Array.prototype.sort if no callback is passed to it will coerce non-undefined elements to strings when sorting. It does do that.

To sort numbers passing a function like (a, b) => a - b is good enough.
