object.seal

ES5 Sham

The Object.seal() method seals an object, preventing new properties from being added to it and marking all existing properties as non-configurable. Values of present properties can still be changed as long as they are writable.

WARNING Silently fails in ExtendScript. This should be fine unless you are depending on the safety and security provisions of this method.
