How do I use a for-of loop in nested loops?

Can you explain how to use a for-of loop in nested loops?

Sure! A for-of loop allows you to iterate over iterable objects like arrays. In nested loops, you can use it to loop through arrays within arrays.

Can you give me an example of that?

Absolutely! Here's a simple example:

const outerArray = [[1, 2], [3, 4]];

for (const innerArray of outerArray) {
    for (const number of innerArray) {
        console.log(number);
    }
}

This will log each number in the nested arrays.

What if I want to access the index of the inner loop?

In a for-of loop, you can't directly access the index. You can use the forEach method or a traditional for loop if you need the index.
