What is actually happening?

• effect run 2 times

The valid array length is from 0 to Math.pow(2, 32) - 1, AKA 4294967295. If a array integer prop is out of valid array length, it will be treated as a object key not a array index.

• adding integer prop less than or equal valid array length to array will change the length of array

• adding integer prop out of valid array length to array doesn't change the length of array

• array.length will never be bigger than 4294967295
