### replacements?

`Record`\<`string`, `string` | `number`>

Optional object containing key-value replacements to interpolate placeholders inside the string.

## Returns

`string`

The localized and interpolated string, or the raw key if not found.

```typescript theme={null}
t("sidebar_confirm_delete_note", "en", { name: "Todo.md" });
// Returns: 'Are you sure you want to delete note "Todo.md"?'
```
