``` let a = new Uint8TypedArray(10); let b = Object.getOwnPropertyDescriptor(a, 0); assert(b.configurable === false); ``` should not fail: by section 9.4.5.1 (https://tc39.github.io/ecma262/#sec-integer-indexed-exotic-objects-getownproperty-p) that applies to integer indexed exotic objects, and section 22.2.7 (https://tc39.github.io/ecma262/#sec-properties-of-typedarray-instances) that says that typed arrays are integer indexed exotic objects.
