How can I handle errors when using JavaScript array methods?

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

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

Sure! Here's an example:

try {
    let arr = [1, 2, 3];
    let result = arr.map(num => {
        if (num === 2) throw new Error('Error: Number is 2!');
        return num * 2;
    });
} catch (error) {
    console.error(error.message);
}

What happens if I try to access an index that doesn't exist?

If you try to access an index that doesn't exist in an array, it will return undefined. You can check for this before proceeding.

Are there any specific array methods that are more prone to errors?

Yes, methods like map, filter, and reduce can throw errors if the callback function has issues, such as accessing undefined properties.
