%TypedArray%.prototype.fill is a distinct function that implements the same
|

algorithm as Array.prototype.fill as defined in 22.1.3.6 except that the this
|
||||
object's [[ArrayLength]] internal slot is accessed in place of performing a
|
||||
[[Get]] of "length". The implementation of the algorithm may be optimized with
|
||||
the knowledge that the this value is an object that has a fixed length and
|
||||
whose integer indexed properties are not sparse. However, such optimization
|
||||
must not introduce any observable changes in the specified behaviour of the
|
||||
algorithm.
