| Fills all the elements with non numeric values values. |
| info: | |
| 22.2.3.8 %TypedArray%.prototype.fill (value [ , start [ , end ] ] ) |
| |
| %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. |
