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. ... 22.1.3.6 Array.prototype.fill (value [ , start [ , end ] ] ) ... 3.
