| 1. Let v be the this value. |

| 3. Return ? SetViewValue(v, byteOffset, littleEndian, "Uint16", value). |

| ... |
| 15. Let bufferIndex be getIndex + viewOffset. |
| 16. Return SetValueInBuffer(buffer, bufferIndex, type, numberValue, isLittleEndian). |

| 24.1.1.6 SetValueInBuffer ( arrayBuffer, byteIndex, type, value [ , isLittleEndian ] ) |
| |
| ... |
| 11. Store the individual bytes of rawBytes into block, in order, starting at |
| block[byteIndex]. |
| 12. Return NormalCompletion(undefined). |
