• 4 no, you can directly change it ... array[index].property = value ... or, as the question implies, to replace an object ... array[index] = newobject – Jaromanda X Commented Feb 19, 2016 at 7:45

You have to modify it directly (assuming You know index)

YourArray[index].ObjectProperty = YourValue

It does not make any difference if it's ES6 or not

If all you need to do is modify a prop in the object, theres no need to remove it from the array.

arr[2].prop = newValue;
