You can test both versions in your browser's console. The first version is just a function, the second version is a snippet that needs the parentheses and argument added.
Examples
< {function snippet here}([1, -44, 65, -105, 12])
> [-105, -44, 1, 12, 65]
How?
The first snippet calls the sort method on the array you pass it. By default, the sort method sorts lexicographical, which is bad for integers (especially multi-digit negative numbers). As such, we have to pass it a callback in the form of an arrow function that takes two elements and subtracts the latter from the former. Depending on the resulting value, the two elements are rearranged: if it is smaller than 0, a
will appear before b
, if it is larger than 0, a
will appear after b
, and if it is 0, both elements will end up next to each other.
The second snippet is nothing more than an encoded version of the first snippet and it takes advantage of the fact that in JavaScript, object.function()
equals object["function"]()
. It also uses empty arrays, !
operators and number casting to generate all kinds of strings, in which the needed characters for the function name can be found. Then the brackets are used once more to get the character at a certain index in the string, and all those characters are concatenated, resulting in the following JavaScript code:
[]["fill"]["constructor"]("return this.sort((a,b)=>a-b)")["call"]
[]["fill"]
equals [].fill
, whose ["constructor"]
is the Function
object. We then call that with a string (which is to be evaluated when the function is called), which is the first function, but notice that the argument has been replaced by this
. To set the value of this
to the argument, we need to call a function on this function, namely ["call"]
. In conventional JavaScript, you would write this as:
function _() {
return this.sort((a,b)=>a-b);
}
_.call(argument);

You realise that anyone who can be bothered to solve this in Brainfuck gets a Lenguage solution with score 128? Alternatively, a single Glypho solution could score 42.

1@Qwerp-Derp Maybe a bit tedious, but certainly doable. In fact, I expect I/O to be the most annoying part (if you don't allow reading input as a list of character codes). – Martin Ender – 2017-03-16T11:39:04.820
Require that all programs run on a reasonable PC in under 5 minutes or something. This makes Language impractical. – Robert Fraser – 2017-03-16T11:59:53.390
@MartinEnder Fixed that issue. – clismique – 2017-03-17T09:31:19.350
1@WheatWizard I was counting only 128 available characters since the challenge specifies ASCII. – Martin Ender – 2017-03-17T17:24:54.657
2I have 3 problems with the language restriction. (1) Restricting arbitrary classes of languages because they would be good at a challange is not fun.(2) most "Normal" programming languages like JavaScript (which already has an answer) do not meet the requirements, which is, certainly not the intent of the restriction, and once again, not fun. (3) I don't think it is really an observable requirement. "Specific function" is not very observable, I could argue through several layers of abstraction that Glypho characters do indeed have specific functions that operate on a set of hidden variables. – Post Rock Garf Hunter – 2017-03-17T18:43:50.923
@WheatWizard A Lenguage/Glypho solution would lead to other trivial solutions, which would win without any extra effort. That kinda detracts from the point of this challenge, IMO. – clismique – 2017-03-17T21:28:32.437
But you are disallowing all sorts of other languages (including some that have already answered) with your current answer just so you can ban two specific languages. IMO this is a sign of a poor challenge. – Post Rock Garf Hunter – 2017-03-17T21:29:47.087
@WheatWizard Fixed it with a new rule. Just not sure if it works, though. – clismique – 2017-03-17T21:35:24.780
@StewieGriffin What I mean by "covered by loopholes" is that illegal answers will get covered by loopholes, not Mathematica/Matlab answers. Sorry for the confusion. – clismique – 2017-03-17T21:36:32.053
