Our default sort converts everything to string, then sorts by UTF-16 code. So yes, [1, 10, 3] is sorted and you are going to live with it.

I'm not sure whether this is satire or not.

It's not. The default sorter does that, because that way it can sort pretty much anything without breaking at runtime. You can overwrite it easily, though. For the example above you could simply do it like this:

[3, 1, 10].sort((a, b) => a - b)

Returns: [1, 3, 10]

Holy shit that's actually true. I just tried it

who the fuck decided that not breaking at runtime was more important than making sense?

this js example of [1, 3, 10].sort() vs [1, 3, 10].sort((a, b) => a - b) will be my go to example of why good defaults are important

who uses utf 16? people either use utf 8 (for files) or utf 32 (for string class O(1) random access)
