| description: > |
| Uses target's internal [[ArrayLength]] |
| 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. |
| 2. Let target be the this value. |
| ... |
| 10. Let targetLength be the value of target's [[ArrayLength]] internal slot. |
| ... |
| 22. If srcLength + targetOffset > targetLength, throw a RangeError exception. |
