| description: > |
| Set values from different instances using the different buffer and different |
| type. |
| info: | |
| 22.2.3.23.2 %TypedArray%.prototype.set(typedArray [ , offset ] ) |
| |
| 1. Assert: typedArray has a [[TypedArrayName]] internal slot. If it does not, |
| the definition in 22.2.3.23.1 applies. |
| ... |
| 23. If SameValue(srcBuffer, targetBuffer) is true, then |
| ... |
| 24. Else, let srcByteIndex be srcByteOffset. |
| ... |
| 27. If SameValue(srcType, targetType) is true, then, |
| ... |
| 28. Else, |
| a. Repeat, while targetByteIndex < limit |
| i. Let value be GetValueFromBuffer(srcBuffer, srcByteIndex, srcType). |
| ii. Perform SetValueInBuffer(targetBuffer, targetByteIndex, targetType, |
| value). |
