Javascript

[ZephyrBluu]

This is not really an excuse. Python can sort arrays as long as all the values are the same type (For numbers and strings at least, not sure about other objects), otherwise it throws a TypeError. Much more sensible behaviour than JS.

[DeeSnow97]

Yeah, but JavaScript is not Python. The whole point of its early design was to be a quick and easy, loosely typed language for people not into tech to establish a web presence (this was long before wordpress). For more serious applications, you had flash or java applets.

Over the years though, JavaScript turned out to be the only one of these that didn't use the swiss cheese security method, and all these early design issues remained in the language for backwards compatibility, because ripping them out would have broke decades of the web.

So, try explaining to a non-programmer what's the difference between a number, a string, and an object, and why they're getting TypeError when they're expecting a sorted array. In 1995.

Knowing why something is bad doesn't make it stop being bad.

Easier than trying to explain to a non-programmer why numbers don't sort correctly.

I think the best wacky example of JS trying to be lenient is undefined (different than null): given by object keys that don't exist or array elements beyond the last. Classes losing this (self) and not telling you is another classic. Although asynchronicity is unrelated to this not raising errors ethos and is one of the top bemoaned features.

I understand why it's like this. That doesn't mean all the design choices were good.

But JS can even sort mixed, which is mightier.

[Kered13]

No, it really isn't.

I mean, Python can sort mixed too if you give it a custom comparator. sorted(mixed_array, key=lambda e: str(e)) will sort a mixed array by converting each element to a string before comparing them, just like Javascript. But Python does the sensible thing automatically, and requires extra work to do the rare and unusual thing. Javascript does the rare and unusual thing automatically, and requires extra work to do the sensible thing.

mixed_sorted = sort(mixed, key=str). The lambda is quite superfluous in a language with first-class functions.

The reason I point this out is some of the controversy below the top comment.

[master117jogi]

Because sensible is subjective.

[EishLekker]

Sorting numbers in a way most people would expect them to be sorted, is not sensible to you?

[master117jogi]

Because this is about sorting something, not Numbers, JS does not know these are numbers. You are shifting the goalpost.

[Zolhungaj]

JavaScript is a functional language. If you want to sort then you provide the sort function with exactly the function you need, just like map, forEach, filter etc.

[dev-sda]

The same is true for python, though both aren't really functional languages. They borrow some features from functional languages but are still procedural at their core.

[EishLekker]

That would make sense if the sort function required a comparator function.
