Sometimes, we want to fix the issue when we call JavaScript array push with multiple objects and gets undefined.

In this article, we’ll look at how to fix the issue when we call JavaScript array push with multiple objects and gets undefined.

How to fix the issue when we call JavaScript array push with multiple objects and gets undefined?

To fix the issue when we call JavaScript array push with multiple objects and gets undefined, we should get the latest value of the array we call push on.

For instance, we write:

const arr = [1, 2, 3]
arr.push(...[4, 5, 6])
console.log(arr)

to call arr.push with the [4, 5, 6] spread as the arguments of push with the spread operator.

Therefore, from the console log, arr is [1, 2, 3, 4, 5, 6] since push appends the values into arr in place.

Conclusion

To fix the issue when we call JavaScript array push with multiple objects and gets undefined, we should get the latest value of the array we call push on.
