description: >
Returns abrupt from value set
info: |
%TypedArray%.prototype.fill ( value [ , start [ , end ] ] )
Let O be the this value.
Perform ? ValidateTypedArray(O).
Let len be O.[[ArrayLength]].
If O.[[ContentType]] is BigInt, set value to ? ToBigInt(value).
Otherwise, set value to ? ToNumber(value).
Let relativeStart be ? ToIntegerOrInfinity(start).
If relativeStart is -Infinity, let k be 0.
Else if relativeStart < 0, let k be max(len + relativeStart, 0).
Else, let k be min(relativeStart, len).
If end is undefined, let relativeEnd be len; else let relativeEnd be ? ToIntegerOrInfinity(end).
If relativeEnd is -Infinity, let final be 0.
Else if relativeEnd < 0, let final be max(len + relativeEnd, 0).
Else, let final be min(relativeEnd, len).
If IsDetachedBuffer(O.[[ViewedArrayBuffer]]) is true, throw a TypeError exception.
Repeat, while k < final,
Let Pk be ! ToString(F(k)).
Perform ! Set(O, Pk, value, true).
Set k to k + 1.
Return O.
IntegerIndexedElementSet ( O, index, value )
Assert: O is an Integer-Indexed exotic object.
If O.[[ContentType]] is BigInt, let numValue be ? ToBigInt(value).
Otherwise, let numValue be ? ToNumber(value).
Let buffer be O.[[ViewedArrayBuffer]].
If IsDetachedBuffer(buffer) is false and ! IsValidIntegerIndex(O, index) is true, then
Let offset be O.[[ByteOffset]].
Let arrayTypeName be the String value of O.[[TypedArrayName]].
Let elementSize be the Element Size value specified in Table 62 for arrayTypeName.
Let indexedPosition be (ℝ(index) × elementSize) + offset.
Let elementType be the Element Type value in Table 62 for arrayTypeName.
Perform SetValueInBuffer(buffer, indexedPosition, elementType, numValue, true, Unordered).
Return NormalCompletion(undefined).
