How do I handle errors in a map function?

How do I handle errors in a map function?

You can handle errors in a map function by using try-catch blocks within the mapping function.

Can you show me an example of that?

Sure! Here's a simple example:

const numbers = [1, 2, 3, 4];
const results = numbers.map(num => {
    try {
        if (num === 2) throw new Error('Error with number 2');
        return num * 2;
    } catch (error) {
        console.error(error.message);
        return null; // or any default value
    }
});
console.log(results);

What happens if I don't handle errors?

If you don't handle errors, your program may crash or produce unexpected results when an error occurs.
