esid: sec-%typedarray%.prototype.fill
description: >
  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.

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

  ...
  7. Repeat, while k < final
    a. Let Pk be ! ToString(k).
    b. Perform ? Set(O, Pk, value, true).
  ...

  9.4.5.9 IntegerIndexedElementSet ( O, index, value )

  ...
  5. If arrayTypeName is "BigUint64Array" or "BigInt64Array",
     let numValue be ? ToBigInt(value).
