We can stored data in variable ... NAME?

[doctor8296]

I found new approuach to store any data in variable name.

const some_interesting_text = 100;
let variable_name;
for (const key in {some_interesting_text}) {
    variable_name = key;
}

variable_name // "some_interesting_text"

With that we can store code, decrypt codes etc etc in variable name. This also can be used as the protection from renaming variables (var names integrity check). We can force user to keep the original name of the variable and variable names can be infinitely long! It will be extremely irratating to work with such code.

We also can keep logic in evals. Example:

let someOutsideEvelVariable = false;
const someOutsideEvelVariableName = (() => {
  for (const key in {someOutsideEvelVariable} ) {
    return key;
  }
})();
eval(`${someOutsideEvelVariableName}=true`);

This is just using the shorthand syntax, which Babel and most tools will support. It did break https://deobfuscate.io/.

path.scope.rename("some_interesting_text", "RENAMED")

const RENAMED = 100;
let variable_name;
for (const key in {
  some_interesting_text: RENAMED
}) {
  variable_name = key;
}
console.log(variable_name); // "some_interesting_text"

Oh, sad. But concept is fire

@MichaelXF and another one!

also it seems it is unredefineable damn, I should've save this for myself

[doctor8296]

This approach works with both class constructors and function constructors. It ensures they cannot be renamed! In essence, it’s a win—no functions or classes can be renamed, and even some variables used to construct a class remain unaffected. So all non-constant variables are safe well. Damn, I am pure evil

With function it was always a thing, idk why I didn't think about that much. Maybe I thought that name can be redefined

Here the shortest version

also interesting thing:

that's funny how you basicaly can put any code in there and it will be reflected in signature (as well as func code lol)
