Accessing variables trapped by closure

Question

I was wondering if there is any way to access variables trapped by closure in a function from outside the function; e.g. if I have:

A = function(b) {
    va         


        

Answer 1

The whole point to that pattern is to prevent 'c' from being accessed externally. But you can access foo() as a method, so make it that it will see 'c' in its scope:

A = function(b) {
    var c = function() {//some code using b};
    this.foo = function() {
        return c();
    }
}
