Calling a function which is inside of a function

My C# oriented braincells keep telling me that this should work:

var MyApp = function() {
currentTime = function() {
    return new Date();
  };
};

MyApp.currentTime();

Clearly it doesn't. But if a javascript function is an object, shouldn't I be able to call a function that is on the object? What am I missing?

You can change your code a bit and use this:

var MyApp = new (function() {
  this.currentTime = function() {
    return new Date();
  };
})();

MyApp.currentTime();

Or you can do this:

var MyApp = {
    currentTime: function() {
        return new Date();
    }
};

MyApp.currentTime();

currentTime is a global (set when you call myApp), not a property of MyApp.

To call it, without redefining the function:

MyApp();
currentTime();

However, it sounds like you want either:

A simple object

var MyApp = {
    currentTime: function() {
      return new Date();
    };
};

MyApp.currentTime();

A constructor function

var MyApp = function() {
  this.currentTime = function() {
    return new Date();
  };
};

var myAppInstance = new MyApp();
myAppInstance.currentTime();
