How can I handle errors when using array methods in JavaScript?

How can I handle errors when using array methods in JavaScript?

You can handle errors in array methods by using try-catch blocks or checking conditions before executing the method.

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

Sure! Here's an example:

const numbers = [1, 2, 3, null, 5];
const doubled = numbers.map(num => {
    try {
        return num * 2;
    } catch (error) {
        console.error('Error processing number:', error);
        return null;
    }
});
console.log(doubled);

What about using filter? How can I handle errors there?

For filter, you can also use try-catch. Here's an example:

const numbers = [1, 2, 3, null, 5];
const filtered = numbers.filter(num => {
    try {
        return num !== null;
    } catch (error) {
        console.error('Error filtering number:', error);
        return false;
    }
});
console.log(filtered);

Are there any best practices for error handling in array methods?

Yes, some best practices include validating inputs before processing, using descriptive error messages, and logging errors for debugging.
