| Values from src array are not cached |

| 1. Assert: array is any ECMAScript language value other than an Object with a |
| [[TypedArrayName]] internal slot. If it is such an Object, the definition in |
| 22.2.3.23.2 applies. |
| ... |
| 21. Repeat, while targetByteIndex < limit |
| a. Let Pk be ! ToString(k). |
| b. Let kNumber be ? ToNumber(? Get(src, Pk)). |
| c. If IsDetachedBuffer(targetBuffer) is true, throw a TypeError exception. |
| d. Perform SetValueInBuffer(targetBuffer, targetByteIndex, targetType, |
| kNumber). |
