Describe a project case where something went wrong and how you dealt with it.

In one of the Node.js projects, there was a situation where, due to improper handling of asynchronous operations, data was being written to the database in the wrong order, leading to errors and inconsistency.

How I handled it:

• Analyzed the code and identified places where promises were not handled correctly.
• Rewrote the logic using async/await for sequential execution.
• Added error handling and logging for quick problem identification.
• Conducted additional tests to ensure the order of operations is maintained.

This helped eliminate the bug and improve the application's reliability.
