esid: sec-%typedarray%.prototype.set-typedarray-offset
description: >
Set values from different instances using the same buffer and same
constructor. srcBuffer values are cached.
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
a. Let srcBuffer be ? CloneArrayBuffer(srcBuffer, srcByteOffset, srcLength,
%ArrayBuffer%).
b. NOTE: %ArrayBuffer% is used to clone srcBuffer because is it known to not
have any observable side-effects.
...
...
27. If SameValue(srcType, targetType) is true, then,
a. NOTE: If srcType and targetType are the same, the transfer must be
performed in a manner that preserves the bit-level encoding of the source
data.
b. Repeat, while targetByteIndex < limit
i. Let value be GetValueFromBuffer(srcBuffer, srcByteIndex, "Uint8").
ii. Perform SetValueInBuffer(targetBuffer, targetByteIndex, "Uint8",
value).
