How can I merge two arrays without using the spread operator?

How can I merge two arrays without using the spread operator?

You can use the concat method to merge two arrays. For example, array1.concat(array2) will combine them.

Can you show me an example with actual arrays?

Sure! If you have const array1 = [1, 2, 3]; and const array2 = [4, 5, 6];, you can merge them like this: const merged = array1.concat(array2);.

What if I want to merge more than two arrays?

You can still use concat. Just chain them like this: array1.concat(array2, array3).

Is there a way to do it using a loop?

Yes! You can use a loop to push elements from one array into another. For example:

let merged = [];
for (let item of array1) {
    merged.push(item);
}
for (let item of array2) {
    merged.push(item);
}
