The Problem: Creating a Looping Prompt

In the situation described, the goal is to display a prompt that presents the user with options, specifically allowing them to select from available choices or exit the application. The user should be able to return to the options page after performing a selected action. The initial code provided fails to achieve this, as it does not rerun the prompt after an option is chosen.

The Initial Approach

The code provided by the user can be broken down into two main parts:

Here’s a simplified view of the initial attempt:

The issue here is that there is no mechanism to loop back to the prompt after an action is taken.

The Solution: Implementing a Loop

To address this flaw, we can define a function that will handle the input and will be called recursively. Here’s an improved structure to allow for the looping functionality:

Breaking Down the Solution

Define a Function: By creating an async function called prompt, you encapsulate the logic for displaying choices and processing user input.

Use Async/Await: The use of await ensures the program waits for user output before proceeding, which is essential for user interaction.

Exit Condition: When the user selects exit, the function simply returns false, effectively terminating the prompt loop.
