typo, wrong return value or parameter name

[FeeYo7]

in README.md the first decorator takes description as a parameter, changes descriptor in the function body and then returns descriptor. I think it should change description in function body and then return description.

Close, outdated?

descriptors seem to be immutable, so if one needs to alter a given descriptor, one has to clone it and then return the clone, possibly modified.

It is my understanding that @nf071590 is referencing the following from the examples in the doc:

function nonenumerable(target, name, description) {
  descriptor.enumerable = false;
  return descriptor;
}

Note that the parameter description does not match the variable used within the function body named descriptor (r vs. n). The fix would simply change the parameter name to descriptor.
