hope this fix your issue The Scope of a function is set when the function object is created, for example:
code :
var fn;
// augment scope chain:
with ({foo: "bar"}) {
  fn = function () { // create function
    return foo;
  };
}​​
// restored scope chain
fn(); // "bar"

I wish this help you I know this is not the recommended way of doing it, but if I declare the following functions, and then invoke them as constructors, what will be the difference (if any) between the resulting objects? , In short:
code :
new something2() instanceof something2 === false
Something.prototype.method = function () { };
something2.prototype.method = function () { };
typeof (new Something()).method === "function"
type (new something2()).method === "undefined"
Object.getPrototypeOf(new Something()) === Something.prototype // steps 5 & 6
Object.getPrototypeOf(new something2()) === Object.prototype // default

I think the issue was by ths following , Make a namespace for other classes or functions you might want to do this with. You don't want to continually pollute the global namespace but there's no reason you can't make one namespace that's global and put your individual things underneath that:
code :
(function($){
  window.MyNamespace = function(){};
  var message = "Something here";

  $.extend(MyNamespace, {
    x: function(){
      alert(message);
    }
  });
})(jQuery)

MyNamespace.x()

it fixes the issue Please feel free to update the tittle to a more appropriate one. I was not sure how to word it. , JSLint is only complaining that your code looks like this:
code :
$(function() {
    $('#a').on('click', a);
});

function a() {
    // ...
}
function a() {
    // ...
}

$(function() {
    $('#a').on('click', a);
});
(function (appLoad) {
    "use strict";
    appLoad(window.jQuery, window, document);
}(function ($, window, document) {
    // ...
}));
(function ($, window, document) {
    // ...
}(window.jQuery, window, document));

wish help you to fix your issue Solution after feedback and additional research
The answer is that BOTH of those functions are function expressions:
code :
var funcExpression = function(){
  alert("function expression");  
}();

(function declarFunc(){
  alert("declared func");  
})();
var foo = function declarFunc(){
  alert("declared func");  
};
