Got it — you’d like the chain of accessed properties to “remember” its path, so you can do things like:
|
||
|
||
```js
|
||
console.log(foo.bar.baz.toString()); // "bar.baz"
|
||
```
|
||
|
||
You can extend the Proxy trick for that:
|
||
|
||
```js
|
||
function Bottomless(path = []) {
|
||
return new Proxy(() => {}, {
|
||
get(_, prop) {
|
||
if (prop === "toString" || prop === "valueOf") {
|
||
return () => path.join(".");
|
||
}
|
||
return Bottomless([...path, prop]);
|
||
},
|
||
});
|
||
}
|
||
|
||
const foo = Bottomless();
|
||
|
||
console.log(foo.bar.baz.toString()); // "bar.baz"
|
||
console.log(foo.hello.world.toString()); // "hello.world"
|
||
```
|
||
|
||
⚡ Notes:
|
||
|
||
- `toString` (and `valueOf`) are trapped so you can stringify naturally.
|
||
- The chain isn’t “real” objects anymore, but function proxies that track their path.
|
||
- You could also add a `.path` property if you prefer structured access.
|

Want me to make it so it **still supports assignment** (`foo.bar = 123`) _and_ path stringifying?
