JSF*ck - How crazy can JavaScript get?

I've discovered JSFuck, the fever dream of a programming language. Its been around since 2012-ish, Its certainly not new but caught my eye recently while surfing through Youtube.

JSFuck - Code anything with only `()+[]!`

We know that JS can be stupid sometimes with a few operations mainly operators, math etc. And that they can return some unexpected values even without any input. By using this method you can practically write anything using these Atomic parts.

JSFuck is a esoteric language surprisingly enough it is plain JS that can run in browsers and NodeJS alike without any additional support like a Framework or a compiler.

If you write +[] in JS it'll return 0, kinda adding nothing to null and getting a 0 -- Nice.
It uses this venerability to create letters, numbers, functions all of it.

Similarly to get an A -- you write (![]+[])[+!![]], Quite the jump!

A traditional 21 character alert("Hello World!") in JSFuck consists of 4325 characters with only the holy characters.

Some Basics:

false       =&gt;  ![]
true        =&gt;  !![]
undefined   =&gt;  [][[]]
NaN         =&gt;  +[![]]
0           =&gt;  +[]
1           =&gt;  +!+[]
2           =&gt;  !+[]+!+[]
10          =&gt;  [+!+[]]+[+[]]
Array       =&gt;  []
Number      =&gt;  +[]
String      =&gt;  []+[]
Boolean     =&gt;  ![]
Function    =&gt;  []["filter"]
eval        =&gt;  []["filter"]["constructor"]( CODE )()
window      =&gt;  []["filter"]["constructor"]("return this")()

The whole code is encoded in a function -- also written in JSFuck. Here's the online Encoder that convers plain JS to this abominated version http://www.jsfuck.com/

While this thing servers no practical use it is fascinating to see how little things in a programming language are used to literally summon a new language. Anyways, I want to encode all my projects in JSFuck just for the sake of it even if they're gonna be a million characters.

Here's console.log("Hello World!") consisting of only 8516 chars that you can run normally :)

Interesting stuff and looks more complicated and longer than the actual JS. I also read about a new language lately, Carbon is it? As a replacement for c++

Haha, its definitely more complicated. Its actually more like a parody, not useful at all.

I've read a few things about carbon, never used it though.
