These files support a JavaScriptCore-only syntax for internal slots. `@` is used to access an internal slot. For example: `new @Array(123)` will create a new `Array` similar to `new Array(123)`, except if a library modifies the `Array` global, it will not affect the internal slot (`@Array`). These names must be allow-listed in `BunBuiltinNames.h` (though JavaScriptCore allowlists some names by default). |
