-  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.

-    ...
-    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).

-  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.

-  7. Return ? OrdinaryToPrimitive(input, hint).

-  5. For each name in methodNames in List order, do
-    a. Let method be ? Get(O, name).
-    b. If IsCallable(method) is true, then
-      i. Let result be ? Call(method, O).
-      ii. If Type(result) is not Object, return result.
-  6. Throw a TypeError exception.
