Error Cause: Enhanced Debugging

In ES13 (ECMAScript 2022), the cause property was introduced for the Error object. This property allows you to chain errors together, making it easier to trace the root cause of an error.

Before ES13: Managing nested errors and providing contextual information often necessitated custom error-handling logic, complicating the debugging process.

With ES13: The new cause property enables you to associate errors, offering additional context about the original error and simplifying debugging.

Here's how it works:

try { 
  ......
} catch (error) {
  if (error.cause) {
    console.log('Original error:', error.cause);
  }
     console.log('Current error:', error);
}        

Benefits of using the cause property:

• Improved debugging: You can easily trace the chain of errors back to the root cause.
• More informative error messages: You can provide more context about the error to developers and users.
• Better error handling: You can handle errors more effectively and appropriately.

This feature enhances error handling by providing greater context, making it easier to trace the root cause of issues. This is crucial for maintaining robust and reliable code.
