8. Can you explain how the process of debugging and troubleshooting differs between these two frameworks?

Debugging and troubleshooting are both important processes in the software development cycle that help identify and fix errors or issues in a program. However, the approach to debugging and troubleshooting can differ between React and Angular.

1. Debugging:
In React, debugging is primarily focused on identifying logical or syntactical errors in the code. React uses JavaScript, which is a dynamic language that may throw runtime errors during execution. This means that developers often use tools like browser developer consoles or IDE debuggers to step through their code and identify where an error is occurring.

On the other hand, debugging in Angular also involves identifying coding errors, but it is more focused on understanding how data flows throughout the application. Angular applications use reactive programming concepts like observables and pipes, which can be difficult to troubleshoot without proper understanding of these concepts. As a result, developers may need to use tools like Augury (a Chrome extension) that helps visualize data flow within an Angular application.

2. Troubleshooting:
Troubleshooting involves identifying and resolving issues that occur during runtime, such as unexpected behaviors or crashes. In React, since it is a lightweight framework with minimal built-in features, troubleshooting often involves manually checking each component or module for any potential bugs.
