-/**
- * This is a TypeScript function that optimistically updates data on the client-side before sending a
- * request to the server and rolling back changes if the request fails.
- * @param {T} model - The object or record that needs to be updated optimistically.
- * @param preUpdate - `preUpdate` is a function that is called before the server update is executed. It
- * can be used to perform any necessary actions or updates on the model or UI before the server update
- * is initiated.
- * @param serverUpdate - `serverUpdate` is a function that returns a Promise representing the server
- * update operation. This function is called after the previous state of the model has been recorded
- * and the `preUpdate` function has been executed. If the server update is successful, the `postUpdate`
- * function is called with the result
- * @param [postUpdate] - `postUpdate` is an optional callback function that will be called after the
- * server update is successful. It takes in the response from the server update as its parameter. If
- * this parameter is not provided, nothing will happen after the server update.
- * @returns A Promise that resolves to `void`.
