I have an object, that contains a status-property. The status gets set by a function internal to that object. This function gets invoked as /init();/ and sets the status-property of the outer function.
If I make that property world-readable via /this/ it will become world-writable, too. Is there any way except of defining a getter function to an inner property? I would like to get the property via /Object.property/ still.

Make it a private property and use a getter.
For example:
function myClass () { this.public = 0; // This property is fully accessible from the outside var private = 1; // This property is inaccessible from outside the object
this.getPrivate = function () { return (private); }

No. There isn't. Any (non-native) Object.property is writable as long as it's visible. Reducing the visibility of the status-property (hiding it into a closure) would protect it, but its getter() would still be r/w anyway, it could be hijacked to return something != status-property. Viva the mutability.
