jsLint erroneous warning

jslint_erroneous_warning.js

var PP = PP || {};

PP.singleton = (function () {
    var foo = function () {
            // jsLint will warn that "bar" is not defined. Which is true in essence, but not in reality
            // since the bar function is defined before it will be possible to call foo, it is not really an issue.
            bar(); 
        },
        bar = function () {
            alert("OMG");
        };

    return {foo: foo};
}());

// Solve this by refactoring to this, and the warning will go away:

PP.singleton = (function () {
    var bar = function () {
            alert("OMG");
        },
        foo = function () {
            // jsLint will no longer warn, since bar has been defined above.
            bar(); 
        };
        

    return {foo: foo};
}());

// If you find yourself unable to rearrage to get rid of this kind of warning
// It most likely means you have a too complicated structure and should refactor!!
