| 22.2.4.5 TypedArray ( buffer [ , byteOffset [ , length ] ] ) |

| This description applies only if the TypedArray function is called with at |
| least one argument and the Type of the first argument is Object and that |
| object has an [[ArrayBufferData]] internal slot. |

| ... |
| 14. Else, |
| a. Let newLength be ? ToLength(length). |
| b. Let newByteLength be newLength × elementSize. |
| c. If offset+newByteLength > bufferByteLength, throw a RangeError exception. |
