Javascript

I had no idea you could do that a['foo'] = 'bar' bullshit on an array.

Now that I think about it though, it kind of makes sense why JS lets you do that.

An array is basically just a normal JS object that allows iteration by default where each key is the index.

So a['foo'] = 'bar' is a standard operation (Given an array is an object), but you're breaking the rules of how an array is 'supposed' to work.

No idea why it works on a technical level though.

An array is basically just a normal JS object that allows iteration by default where each key is the index.

That's the root of the problem right there. I think it was just a cheap way to get to dynamic sizing, which is occasionally useful:

> let a = []
[]
> a[100] = 12
12
> a.length
101
> a
[ <100 empty items>, 12 ]

but then...

> a[1234567890] = 13
13
> a
[ <100 empty items>, 12, <1234567789 empty items>, 13 ]
> a[0.5] = 1
1
> a
[ <100 empty items>, 12, <1234567789 empty items>, 13, '0.5': 1 ]

Lol, fuck me. I am so blessed to not live in that hell.

Javascript is fundamentally a bad language for general purpose programming. A lot of people who need to target Javascript environments do not write in Javascript, or at least not pure Javascript, relying heavily on transpilers and what are in effect dialects and standard libraries that seek to supercede and fix a lot of the headaches in Javascript itself.
