But transparent getters and setters can be used to emulate private or immutable properties:
function Foo() {
var _bar = 42;
return {
get bar() {
return _bar;
}
}
}
var foo = Foo();
foo.bar
/*
42
*/
However the fact that you can transparently replace a simple property by a computed one (e.g. for backwards compatibility or to trigger side effects in observables) does make explicit, Java-style, getters and setters less useful.
