What is the purpose of the finally block in JavaScript?

The finally block in JavaScript is used to execute code after try and catch blocks, regardless of whether an error occurred.

Can you give me an example of how to use it?

Sure! Here's a simple example:

try {
    // Code that may throw an error
    let result = riskyFunction();
} catch (error) {
    console.error('Error occurred:', error);
} finally {
    console.log('This will run regardless of the outcome.');
}

What happens if there is no catch block?

If there is no catch block, the finally block will still execute, but the error will propagate up the call stack.

Is it possible to skip the finally block?

No, the finally block will always execute after the try and catch blocks, unless the program is terminated.
