What is the difference between try, catch, and throw in programming?

Can you explain the difference between try, catch, and throw in programming?

Sure! In programming, 'try' is used to wrap code that might throw an error, 'catch' handles the error if it occurs, and 'throw' is used to create a custom error.

How do I use them in a practical example?

Here's a simple example:

try {
    // Code that may throw an error
    let result = riskyFunction();
} catch (error) {
    // Handle the error
    console.error('Error occurred:', error);
} finally {
    // Code that runs regardless of error
    console.log('Execution completed.');
}

What happens if I don't use catch?

If you don't use 'catch', any error thrown in the 'try' block will cause the program to crash, and you'll see an unhandled exception.

Can I throw my own errors?

Yes, you can throw your own errors using the 'throw' statement, like this: throw new Error('My custom error message');.
