Can Object.assign handle arrays?

Can Object.assign handle arrays in JavaScript?

No, Object.assign is primarily used for copying properties from one or more source objects to a target object. It does not handle arrays as you might expect.

What happens if I try to use Object.assign with arrays?

If you use Object.assign with arrays, it will treat the array as an object and copy properties based on their keys, not the values.

Can you give me an example of that?

Sure! If you have an array like [1, 2, 3] and use Object.assign({}, array), it will result in { '0': 1, '1': 2, '2': 3 }.

So, how should I merge arrays instead?

To merge arrays, you can use the spread operator or Array.prototype.concat.
