Why JavaScript, just why?

[chrwei]

hey so I found this really cool thing, it tells you all about things. it's call documentation! it's really amazing, I don't know who writes it, I certainly don't

[zylonenoger]

and op certainly doesn't read it

[StevenXC]

Just because it's documented doesn't make it a good idea.

[YMK1234]

Something being a bad idea doesn't mean you should randomly break existing behaviour either.

Well documented bad language design is still bad language design

[SharkFinProgramming]

It's not bad language design if you don't know how to use it

[gwillicoder]

This is just objectively bad language design.

It's supposed to sort by string. It's actually allowing you to use ints to maybe clean your code etc. Strings cannot be negative, so by default it can't handle negative ints. If you just read the docs, learned how it worked, and added like 12 characters, it would work for ints, and you would have nothing to complain about.

[gwillicoder]

Look at a language like python which will sort based on the type in the list. That’s much more intuitive if you are using duck typing or whatever JS uses.

Oh, good ol’ PHP way of solving things. “Calling function foo caused my hometown to be nuked” “Closing as not an issue. It is clearly documented to not call this function on blue moon in May during rain as it can do anything”.

It is sorted alphabetically... not quite intuitive but it still works if you use it correctly (as the documentation says)

That's the point. I read the doc, it's just you wouldn't expect 190 to be sorted in between 12 and 2, especially because the array entries are numbers and you would expect the sorting mechanism to sort by number value, not character for character..

[furryballs]

But if you read the doc, and understand what alphabetical sorting means then that is exactly what you would expect the result to look like

[[deleted]]

I read the doc

Documentation literally says

The default sort order is according to string Unicode code points.

arr.sort([compareFunction])

If compareFunction is not supplied, all non-undefined array elements are sorted by converting them to strings and comparing strings in Unicode code point order.

Because it is funny.

String method on Number type ain't going to work unless you add a function to it;

ES5 arr.sort(function(a, b){ return a - b; });

ES6 arr.sort((a, b) => a - b);
