How do I use try-catch in JavaScript?

You can use try-catch to handle errors in JavaScript. Wrap the code that might throw an error in a try block, and handle the error in the catch block.

Can you give me an example?

Sure! Here's a simple example:

try {
    // Code that may throw an error
    let result = riskyFunction();
} catch (error) {
    console.error('Error occurred:', error);
}

What happens if I don't use try-catch?

If you don't use try-catch, any error thrown will stop the execution of your script and may lead to an unhandled exception.

Are there any best practices for using try-catch?

Yes! It's best to use try-catch for specific code that may fail, avoid using it for control flow, and always log errors for debugging.
