Anything is possible! Unlocking the Nightmarish Power of JavaScript..
summary
Shows how with + Proxy breaks the scope chain so identifiers resolve to lazily generated properties, demonstrates getters and proxy get traps that run eval on property names, and builds concrete demos: an on‑the‑fly binary literal demo, PHP‑style bareword strings, and a typed‑variable shim using double‑dollar names. Code runs live in a REPL, uses real proxy traps for debugging and mutation, and is explicitly fragile and exploratory — ideal for JavaScript internals fans, not for production patterns.
