  22.2.4.4 TypedArray ( object )

  This description applies only if the TypedArray function is called with at
  least one argument and the Type of the first argument is Object and that
  object does not have either a [[TypedArrayName]] or an [[ArrayBufferData]]
  internal slot.

  ...
  8. Repeat, while k < len
    ...
    b. Let kValue be ? Get(arrayLike, Pk).
    c. Perform ? Set(O, Pk, kValue, true).
  ...

  9.4.5.5 [[Set]] ( P, V, Receiver)

  ...
  2. If Type(P) is String and if SameValue(O, Receiver) is true, then
    a. Let numericIndex be ! CanonicalNumericIndexString(P).
    b. If numericIndex is not undefined, then
      i. Return ? IntegerIndexedElementSet(O, numericIndex, V).
  ...

  9.4.5.9 IntegerIndexedElementSet ( O, index, value )

  ...
  3. Let numValue be ? ToNumber(value).
  ...

  7.1.3 ToNumber ( argument )

  Object, Apply the following steps:

    1. Let primValue be ? ToPrimitive(argument, hint Number).
    2. Return ? ToNumber(primValue).

  7.1.1 ToPrimitive ( input [ , PreferredType ] )

  ...
  4. Let exoticToPrim be ? GetMethod(input, @@toPrimitive).
  5. If exoticToPrim is not undefined, then
    a. Let result be ? Call(exoticToPrim, input, « hint »).
    b. If Type(result) is not Object, return result.
    c. Throw a TypeError exception.
