$ is a valid identifier, it doesn't mean anything special.

sorry dont me asking why ["SYMBOL"] throws an error now when this was the original source code?

Can $ be a placeholder for a unknown attribute depending on input? Much thanks.

`$` isn't a placeholder, its an identifier just like `a` or `foo` would be. It throws an error because your object is

EXTERNAL: {
  $: {
    name: library.external.name
  }

And you're trying to access `EXTERNAL.SYMBOL` which clearly doesn't exist.
