Possible. I assumed, because String.prototype.length does not seem to be
generic (in the sense that, say, String.prototype.trim() is).
Object.getOwnPropertyDescriptor(String.prototype, "length")
{ value: 0,
writable: false,
enumerable: false,
configurable: false }
In contrast, trim() is clearly borrowed from the wrapper’s prototype:
> "".trim === String.prototype.trim
true
ES-262, Sect. 8.4 only says: “The String type is the set of all finite ordered
sequences of zero or more 16-bit unsigned integer values” (etc.). It does not
mention how indexed access or length is handled.
