/**
* 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`.
