| Set values to target and return undefined |
| info: | |
| 22.2.3.23.1 %TypedArray%.prototype.set (array [ , offset ] ) |
| |
| 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 |
| Let Pk be ! ToString(k). |
| Let kNumber be ? ToNumber(? Get(src, Pk)). |
| If IsDetachedBuffer(targetBuffer) is true, throw a TypeError exception. |
| Perform SetValueInBuffer(targetBuffer, targetByteIndex, targetType, kNumber). |
| ... |
| 22. Return undefined. |
