Example Usage of `_getUserById` Method

The _getUserById method is a function that retrieves user information by passing a userid and a callback function. The userid is the identifier of the user you want to fetch, and the callback function is executed once the user data is retrieved.

Syntax:

Parameters:

userid: This is the unique identifier for the user you want to fetch. It could be a string or a number, depending on how user IDs are managed in your system.

callbackFunction: This is the function that will be executed once the user data is retrieved. This function typically receives the user data as a parameter.

Example Code:

In this example:

The userid is "12345". Replace this with the actual ID of the user you want to retrieve.

The handleUserData function will be executed once the user data is fetched. The user data will be passed to the handleUserData function, which you can then use to display, manipulate, or store the user information.

This method is useful when you need to retrieve specific user details asynchronously and then process the data within the callback function.
