| Throws a TypeError if key has a numeric index and object has a detached buffer |
| info: | |
| 9.4.5.5 [[Set]] ( P, V, Receiver) |
| |
| ... |
| 2. If Type(P) is String, then |
| a. Let numericIndex be ! CanonicalNumericIndexString(P). |
| b. If numericIndex is not undefined, then |
| i. Return ? IntegerIndexedElementSet(O, numericIndex, V). |
| ... |
| |
| 9.4.5.9 IntegerIndexedElementSet ( O, index, value ) |
| |
| ... |
| 3. Let numValue be ? ToNumber(value). |
| 4. Let buffer be the value of O's [[ViewedArrayBuffer]] internal slot. |
| 5. If IsDetachedBuffer(buffer) is true, throw a TypeError exception. |
