How can I implement custom error handling in my application?

You can implement custom error handling by creating a centralized error handler that captures exceptions.

Can you give me an example of a custom error handler in JavaScript?

Sure! Here's a simple example:

function errorHandler(err) {
    console.error('Error occurred:', err);
    // Custom logic here
}

try {
    // Code that may throw an error
} catch (err) {
    errorHandler(err);
}

What about error handling in Python?

In Python, you can use try-except blocks. Here's an example:

try:
    # Code that may raise an exception
except Exception as e:
    print('An error occurred:', e)
    # Custom error handling logic

Are there best practices for error handling?

Yes, some best practices include logging errors, providing user-friendly messages, and avoiding silent failures.
