| 2. If Type(P) is String, then |
| a. Let numericIndex be ! CanonicalNumericIndexString(P). |
| b. If numericIndex is not undefined, then |
| i. Perform ? IntegerIndexedElementSet(O, numericIndex, V). |
| ii. Return true. |

| Assert: O is an Integer-Indexed exotic object. |
| Assert: Type(index) is Number. |
| If O.[[ContentType]] is BigInt, let numValue be ? ToBigInt(value). |
| Otherwise, let numValue be ? ToNumber(value). |
