Question

In this javascript code f.init() control the entire flow of the program:

var f = function() {
    return {
        init: function(var1) {
            try {
                f.f1(1)
            } catch (e) {
                alert(e);
            }
            try {
                f.f2(1)
            } catch (e) {
                alert(e);
            }
            // ...
            // more try-catch blocks                
            // ...
        },
        f1: function() {
            throw Error('f1 called');
        },
        f2: function() {
            throw Error('f2 called');
        }
    };
}();

f.init();

How I could centralize all exceptions management in only one try-catch block? Something like this:

var f = function() {
    return {
        init: function(var1) {
            f.f1(1) // this cut the control flow if thrown some error
            f.f2(1) // so this is not called
        },
        f1: function() {
                throw Error('f1 called');
        },
        f2: function() {
                throw Error('f2 called');
        }
    };
}();

try {
    f.init();
} catch (e) {
    alert(e);
}

The previous code cut the flow after thrown some error.

You can’t. Once an error is thrown, the program flow breaks.
