You can convert any Javascript code into these characters:
()[]{}!+
and only these characters.
Here's how:
Numbers
We can get 0 by ...

Reminds me of Brainfuck for sure, I love these sort of little esoteric-toy-language thingies!
Yeah, the 6-character version is actually called JSFuck!
You crack me up, I can't believe you said it reminds you of Brainf**k. You got jokes. 😂 😂
i mean, i sometimes have difficulties reading code but this line:
is this a virus injection in js 😂
Hahaha, looks like it! 😂 It's so fun
yeah, imagine you have to debug entire function written like this. good luck with that 😂😌
No problem! I know, I know, we'll use sourcemaps 😜😂🤣
What the F**k is that!! 👿
I've discovered that actually is a language ! Anyway nice article
F**k JS... I mean JSF**k. 🤪
I believe you only need 6 characters -
()+[]!There's a converter to encode normal javascript here
Yeah! I mentioned this at the end of the article. It's very complicated and I don't know how it works, so I went for the less complex 8 character one 😅
I'm too hungover for this...
I tried the link for JSF... and converted the line: console.log("Hello");
I pasted the result in a file and executed it with node and got this...

What am I missing here???
brilliant! lol
Awesome post, very nice explained! 👏🏻👏🏻
Thank you!
Super cool article there you have my unicorn vote. Correct me if I am wrong but where it says 'The third character here would be p.' I believe you meant 'The fourth character...' because the fourth characters on http/https is p.
Yes you are correct!
Just great information you have shared. Thanks a lot :). After reading this post. I feel like I know nothing about JS. :(.
Nooo don't think that way! This post is just crazy haha
yeah. but this is damn good information.
Hahahhaa... JS fvck
Thanks for this amazing tutorial.
Would this be at all useful for obfuscation?
Yeah it could be!
More compact implementation for some chars here: github.com/TiTi/jswtf/blob/master/...
Hogwarts will be sending you a letter shortly because this is some of that Tom Riddle magic
That's like the anti minifier . compiling normal js to this notation actually makes the codes bigger. Very nice !
