		### s.offset

		Sets the offset property to adjust the incoming position for the following APIs: `slice`, `update`, `overwrite`, `appendLeft`, `prependLeft`, `appendRight`, `prependRight`, `move`, `reset`, and `remove`.

		Example usage:

		```ts
		const s = new MagicString('hello world', { offset: 0 });
