+  SharedArrayBuffer( length )

+  1. If NewTarget is undefined, throw a TypeError exception.
+  2. Let byteLength be ? ToIndex(length).
+  3. Return ? AllocateSharedArrayBuffer(NewTarget, byteLength).

+  ToIndex( value )
+
+  1. If value is undefined, then

+  2. Else,

+    b. If integerIndex < 0, throw a RangeError exception.
+    c. Let index be ! ToLength(integerIndex).
+    d. If SameValueZero(integerIndex, index) is false, throw a RangeError exception.
