+ Throw TypeError from OrdinaryToPrimitive when setting a property
+info: |
+ 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.
+ ...
+ 7. Return ? OrdinaryToPrimitive(input, hint).
+
+ OrdinaryToPrimitive
+
+ ...
+ 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.
