How can I handle errors in JavaScript effectively?

You can handle errors in JavaScript using try-catch blocks, promises, and async/await for better error management.

Can you give me an example of using try-catch?

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 handling errors in asynchronous code?

For asynchronous code, you can use try-catch with async/await:

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

Are there any best practices for error handling?

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