| Throws a RangeError if ToInteger(byteOffset) modulo elementSize is not 0 |
| info: | |
| 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. |
| |
| |
| Let elementSize be the Number value of the Element Size value in Table 56 for constructorName.* |
| |
| ... |
| If offset modulo elementSize ≠ 0, throw a RangeError exception. |
| ... |
| |
| * Int8Array, Uint8Array, Uint8ClampedArray all have element size 1, so will never fail. |
