    Not gonna work on Firefox, since according to the doc, Error.prepareStackTrace is an optional API and only implemented by V8.

    This reminds me of "Creators admit Unix, C hoax" (e.g. https://www.gnu.org/fun/jokes/unix-hoax.html)

    > We stopped when we got a clean compile on the following syntax:

        for(;P("\n"),R--;P("|"))for(e=C;e--;P("_"+(*u++/8)%2))P("| "+(*u/4)%2);

      How Perl was created:

      ‘Larry, throw the cat at the keyboard!’

      MEEEOW!

      ‘What did it type?’

      ‘&}Ak'>v=4%Qe}9;’

      ‘OK, so let’s make this a syntax for hello world.’

      Object.prototype.message='alert\x281337\x29';Array.prototype.toString=Error.prototype.toString;Error.prepareStackTrace = Function;const x = new Error;x.valueOf=x.stack;+x;
    
    Well, that's a mouthful! So many years and JavaScript still can do the most amazing, weird, awesome, scary, obscure, and sexy things in the world of coding.

    I love this. This is a fun hack, but the article also hearkens back to pre-LLM days when people were still interested in _code_.

    JavaScript is so cursed.

      If I were to write a book on programming in JS, it would be a black cover with the JS Holy Trinity equality diagram in red, to emphasize its Satanic nature.

    What's the purpose of the +x at the end?

      The unary plus implicitly converts an expression to a number, which calls `valueOf` for non-primitive values.

      I think to implicitly trigger the valueOf function.

    GPTzero says this entire thing is AI generated for those concerned.
    • user____name 10 minutes ago
      GPT also thinks Frankenstein and Moby Dick are 100% AI last time I checked.

      Doesn’t feel LLM-y to me. If it is LLM-generated, the LLM must have been explicitly instructed to ignore sentence capitalization and invent a persona (‘i chose...’).

      Aha, that's a great reassurance then! ;-)

        Ironic in a good way, you mean? Like employing a counterfeiter to help identify counterfeits?

        Regardless, I don't think it's correct on this one.
