What are exceptions in Node.js and how do I handle them?

Exceptions in Node.js are errors that occur during the execution of your code. You can handle them using try-catch blocks.

Can you give me an example of using try-catch in Node.js?

Sure! Here's a simple example:

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

What about asynchronous code? How do I handle exceptions there?

For asynchronous code, you can use try-catch with async/await or handle errors in the promise's catch method.

Can you show me an example of error handling in an async function?

Absolutely! Here's an example:

async function fetchData() {
    try {
        let data = await getDataFromAPI();
    } catch (error) {
        console.error('Error fetching data:', error);
    }
}
