+  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 )
+
+  ...
+  5. If arrayTypeName is "BigUint64Array" or "BigInt64Array",
+     let numValue be ? ToBigInt(value).
+  ...
+
+  ToBigInt ( argument )
+
+  Object, Apply the following steps:
+    1. Let prim be ? ToPrimitive(argument, hint Number).
+    2. Return the value that prim corresponds to in Table [BigInt Conversions]
+
+  BigInt Conversions
+    Argument Type: String
+    Result:
+      1. Let n be StringToBigInt(prim).
+      2. If n is NaN, throw a SyntaxError exception.
+      3. Return n.
